1. What is the difference between thin client & thick client?Thin Client is a browser based version, whereas thick client is a desktop based version. In thick client, you have lot of functions andformatting options. Desktop Intelligence is full client. It is 2 tier architecture, where Web-I is 3 tier with Enterprise server in between.Desktop-I and Web-I differs in some syntaxes.E.g: [] in Web-I, in Deski.Also scheduling can be done directly in Web-I (Xi R2), where as we need additional software to schedule Deski reports.You can view the Deski reports in Web-I, but not Web-I reports in Deski.But we can schedule the Deski reports via Web-I.WebI: it is 3tier architecture. and also known as thin client . in boxir2 wise merge option available,edit sql also.scheduling directly, Reports will generate not only corporate doc's, others also(excel,pdf--),hide option is not available,Deski: it is 2 tier architecture & also known as full client. Here hide option, edit Sql, rank optionsare available. Desktop intelligence reports are dynamic. desktop intellegence is window base tooland need installation on every PC where asWebI is web base tool and can be access any where through interenet explorerCrystal reports are static and pagewise.Infoview: WebI is a part of infoview. it generates java based reports. while open the reports through infoview.

2. In BOXIR2 we have following tools.Import WizardReport Conversion ToolRepository Migration Wizard

3. Multi pass SQL:Multipass: Breaking one large SQL into multiple SQLs.If you are using the star schema with two or more fact tables,and you enable this

feature, BO will automatically generate two or more SQLs (i.e. one SQL for each fact table object used in the report). Then the results will besynchronised in the report.

4. what is isolated joins in check integrityIsolated join is the join which is not included in any of your contexts, so you are getting that error.Solution : First of all find what are all the joins you left without including in any of your contexts and join them to any of the context whichyou think appropriate.

5. Migration Process:To migrate the bo 6.5 to XIR2:--a) open the migration wizardb) select ur source location(Here give ur BO 6.5 doc)c) click next d) select ur destination location (ur BoXIR2 environment)e) select the users or admin or specific usersf)click next f) click ok.

6. Difference b/w Break & section?Break removes duplicates but the same thing cannot be done by section. Break displays data within the same cell content and Sectioningappears outside the grid. When you do any arithmetic operation on break say sum or count, you can see the sum for individual block and forall the blocks in bottom. In Section it performs operation only on individual block.

7. What is master-detail report?Master-Detail report allows us to display the result in Section wise. It splits large blocks of data into sections. It minimizes the repeatingvalues. We can have subtotals also.It displays the data section wise. If you have the following in a report, for e.g. Country, Store, Sales, you can change it into a master detailreport country wise by dragging and dropping Country as a section when the cursor shows the text 'Drop here to create a section' you cansee the data country wise.

8. how big is ur teamin my enviroment their are 1500 Business End Users and 4 report Developers and Two Universe Designer and one Administrator.

9. is it possible to creating reports without universe.it is possible to creating reports without universe. By Using personal data files&free hand sql. This is possible only in deski reports not inWebI.

11. how to solve #multivalue, #syntax, #error. iwant complete solution process in practical wise?#Multivalue :- this error will occur in 3ways1) #multivalue in aggregation2) #multivalue in breaks header or footer3) #multivalue in section level.


2/32

1:-- the o/p context not include i/p context its situation this error occurs.Ex: in a report i have year,city dia's & Revenue measure is there.

= In The above condition will to run the query getting revenue column #multivalue error occurs.solution: cilck the formulabar in view menu

select the error containg cell, edit the formula to write below condition.= In(,) In The above formula will run correct data will appear in the report.Note: the above condition by default it will take agg "sum" function.#syntax:--the variable in the formula no longer exist in the condition.Ex:- * The above condition will run this error will occur.Solution:- Click edit dataprovider--> new object will be need --> select error cell --> edit formula --> click ok.#error:-- the variable in the formula is incorrect. this error will occur.solution : go for data menu --> click variableselect the error containing a cell --> copy the formula inedit menu --> paste it in new cell --> go for formula bar inview menu --> --> take the first error containg cell-->edit the formula --> repeat the above steps.

12. What is the difference B/W Variable & Formula?Whenever we execute the formula , the result will be stored in the variable.

13. what is meant by incompatible object error in the report level?

When the contexts are not properly defined we will get the error as incompaitable combination of objects.14. In a report i want to fetch the data from 2 data Providers. which condition will satisfy to link the 2 data providers. ex: Q1 havecolumns A,B,C Q2 has a X,Y,Z columns. requirement is like i want to get all the columns from those 2 tables in report level..like A,B,C,X,Y,Z in asingle report.in BOxir2 wise it is possible. would u have base uni & dervied uni's. i think ur requirement is solve byusing "combining query" option & just select "union" operator wise ur query is solve. anotherwise u go for WebI, select "MERGE" option it ispossible. otherwise, ur requirement is not possible. because ur columns names are not maching.u go for deski, select "datamanager" --> click "link to" Option it is possible.

15. What is meant by For each For all function. In which case we use the option in BO?for each-add all objects to the context for all-delete all objects from the context we use forall for summary purpose and foreach fordetail purpose

16. how we improve the performance of report and universe?By creating the summary tables and using aggregate awareness.

17. In xir2 how to send reports to end userYou can send reports to any user via the scheduling options for a report. The report will then run as per the scheduled options and whensuccessful, it will send a copy to the user's email address or inbox (in BO), depending on the options selected.

18.which is the best way to resolve loops? Context or Alias?in a schema we have only one look loop u can create Alias. But, when we have multiple look up u can create contexts. most of the cases areusing context can be use to resolve the loops. why because more number of complexity loops and also schema contains 2 or more fact tablesin ur universe design. If there are more than one fact table use a context or if only one fact table use alias.

19. How do we link 2 universes?The linking can be done at reporter level by linking of data providers. We can link the dimensions and measures of two different universeswith 2 different connections by linking the data providers built upon them.

20. What r the types of joins universe supports?Inner Join, outerjoin, left, right outer join, full outer Join.

21. What r the universe connection types?Shared connectionSecured connectionPersonal connection - used only stand alone system.

22. what r the advantages of creating the universe?The main fact behind creating universes is "Business users need not have strong SQL back ground. But sometimes they need to developreports". In such case the importance of universe comes. The universe designer needs to have a strong SQL back ground and he/she willcreate universe which in turn has objects like dimensions, measures, etc,...


3/32

The business user then uses these objects just by dragging and dropping in the query editor pane. Dragging, dropping and running is moreeasy for him rather than writing SQL by his own.

23. How do u drag 2 sources from 2 diff data providers, how we take these 2 sources into 1 single report?By using data synchronization Option.... synchronization is the term used to describe the merging of data from multiple data sources into asingle block in a report

24. what is merged dimension in 6.5 and webi?in xi r2 they introduced Merged dimension concept to synchronize the multiple data providers in webi by merging them on commondimension...

25. Aggregate Awareness?Aggregate awareness is a term that describes the ability of a universe to make use of aggregate tables in a database. These are tables that contain pre-calculated data. You can use a function called @Aggregate Aware in the Select statement for an object that directs a query to berun against aggregate tables rather than a table containing non aggregated data. Using aggregate table s speeds up the execution of queries,improving the performance of SQL transactions. The reliability and usefulness of aggregate awareness in a universe depends on the accuracyof the aggregate tables. They must be refreshed at the same time as all fact tables. A universe that has one or more objects with alternativedefinitions based on aggregate tables is said to be aggregate aware. These definitions c orrespond to levels of aggregation. For example, anobject called Profit can be aggregated by month, by quarter, or by year. These objects are called aggregate objects.Queries built from a universe using aggregate objects return information aggregated to theappropriate level at optimal speed.

26. What is BO Main Key?BO Main key will store the address for repository of the security domain. General path for BOMainKeyC:\Program Files\Business Objects\BusinessObjectsEnterprise 6\LocData

27. How to Link 3 fact tables?Fact tables are tables with lots of measure values and are uniquly identified by a key, also a fact table can have aforeign key. For Example custumer fact table is connected to loan fact table via customer_id, and each record in loanfact table is uniquely identified by a primary key on cod_acct_no. Similarly customer table can be connected toSavings fact table through customer id.

28. What is hierarchy & Drilling?Heirarchies will be used in drill reports. We will select Drilling levels in Query panel.There are 4 types of levels are there.1.level2.level3.level34.custom level

drill down --->navigation of levels,like one by onedrill through--->selecting new level of heirarchy at the time drillingdrill by--->directly selecting required drilling levelso,from your point a-b-c is drill down . a-->c is drill by

29. How to Hide rows & columns in a report ?hide the colomn ---menu>formate>table formate>pivote>hide button,Rows can be hide only when the break is applied on a particular column using...Format-->Breaks-->Fold30. What do u mean by Merged dimensions in B.O.? merged dimension is nothing but to synchronize the data from different data sources with a common dimension. Web Intelligence allowsyou to synchronize multiple data providers in the same document. This allows you to build reports which synchronize data from multiplesources. When you synchronize queries through merging, you can include report objects from different queries in the same report block.

31. What we have to do to increase performance tuning & to decrease the response time of a report.if we run a report it is taking so much time to display the result to be fallowed as :1) use aggrigate tables(contains pre caliculated data)2)pre defined conditions,LOV's3)Summary tables.in a real time scenario query contains a large if statements. sometimes we need to wait max of 30 min to run particular statement...not allIf the question is not pertaining to query optimization, I would prefer not to use much of formatting on the page. One can keep the report without formatting. Try not to use the slice & dice panel as this would also take considerably long time.

32. What is Full path Client?Full path client is nothing but an info-view.

33. How to sort on a particular object, that object is not picked up while creating the cross tab but we need to sort on the object that is not in the cross tab????


4/32

Go to Format--Sorts then click on Add. We will get all the objects select the object and apply it. which is not in the Cross tab report.34. How can we retrieve particular number of rows from data ware house? For EX: my report wants to display with 10 records in areport? How?We can do this in 2 levels in BO.1. In Universe parameters, set the no of records for your requirements. But I will apply to all reports.2. We can do this to a particular report in the query panel.Select OPTION button (Left side down placed) and set the no of records how many you want.

35. What is custom sorting?Custom sorting is nothing but sorting as per our requirement suppose months likejanfebmaraprmayjunjulWe can display first jan next mar next jun for these purpose we can use custom sort

36. How do we apply sql query on selected variables?If u drag the variable, automatically sql query will be added Or if u select new variable, one window will appear. In this window u select thequalification (dimensional or detail or measure) in definition window. Go for formula tab, window will appear here write a formula by usingobjects & operators.if u have any errors or not plz check once parse condition. Click apply > click ok.

37. what are the differences between web intelligence reports and crystal reports ?bo reporting is prefered for dwh,where as crystal is preferred for transaction database which involves lots of queries and joins.WebI : it is ad-hock reporting. we can change the report as per requirement for management quick decisions. for management CrystalReports:it is standered reportingdaily transactions(example bank ,shopping malls)for production users.38. What is Fan Trap & Chasm Trap?1) FANTRAP PROBLEM solved by ALIAS METHOD:Definition: Two One-to-many table link eachother is in turn

linked another one-to-many table.2) CHASM TRAP PROBLEM solved by CONTEXT METHOD:

Definition: Two Many-to-one table converges on one single lookup table.Loop can be detected while INTEGRITY CHECK is done. Anoption is there as "Check for LOOPS" available. By "Detect Loop" we can choose what to be applied for solving the loop.39.How do u migrate from 6.5 to XI ?migration is done with the help of import wizard in xir2.other wise u can manually migrate universe or report. when u try to open a 6.5 or 5x versionreport or universe they will automatically updated to xi and they cannot open again in theprevious version once they converted to xi. that is why it is better to take a back up beforemigration.40. What is metrics?A metric is the measure of actual performance. A metric is defined using objects in the universe.These are used to track trends and productivity41. What is Dashboards?Dashboards is nothing but collection of information42. IN BOXIR2 creating universe by using Designer and Business View. What is thedifference b/t two?Business view is used to create a lovs in crystal reports. This can be schedule to refresh to daily.business view can be used by only in crystal reportsa universe can also be a source for crystal reports as well as web intelligence.in business view we can connect to multiple database and create a business view, it is not there inuniverse43. Why do we use crystal reports rather than web intelligence reports?Crystal reports: we use most of the times daily basis. we have to know the day to day status.Example daily transactionof the persons in a bank. End of the day whole sales reportsof the same branch. It is for production .it is a predefined template


5/32

eb I: it is only for manage ment users.they want to take own decessions for their ownlike take a sales mall giving offers like end of season sale and clearence sales occational offers.Webi report- it is ad-hoc report, we can modified as perrequest and analysis the reports.but in Crystal reports--> we cant not modify the reportsand it contains daily bases i.e., day to dayinfromation .example: shopping mall and customer details in bank.44. What is chasm trap & Fan Trap?Fantrap means one-to-many joins of the tables it is

detected by visval analysis. By using fantrap problem ismany rows than expected. Through aliases,context and check mutiple sql statements for each measures option we cansolve this problem.chasm trap means two or more many to one joins converge onto a single lookup tableChasam Trap:chasm trap means many-to-one and one-to-many join relationconverge on to a single lookup table, because of this weget incorrect results i.e., cartision product, We willresolved by using some times alias, some times context,some times shortcut join and check mutiple context for eachmeasures option.Fan Trap:Fantrap means one-to-many and one-to-many join relation of the tables it is detected by visval analysis, because of this we get incorrect results i.e., cartision product,We will resolved by using some times alias, some timesshortcut join and check mutiple sql statements for eachmeasures option.45. How many universe dfi you create if you have 2 years of experience in BO ?1. Two Universe2. Depends on my data base and my project. example.in my project if i have 100 tables i willcreate 6 universe.any way u have a two years of exp in bO .u dont have chanceto create universe.we need min 5 to 6 + exp and good domainknowledge

46. Iam having an report there four cloums and n number of rows if i click ang onecell the report want to go to another report page which gives the detail of the cellwhich i click pls help me with exampleThis is hyperlinking.The cell can be defined as a hyperlink and parameters can be passed to the destination report to open.47. Iam having an report it contain n number of rows i want to desplay each rows inone colurInsert a vertical table on the existing table or click dragdrop the rows into columns.BY USING ALETER we can display each row in different colour.48. What are the Errors in BO Pls Explain with Examples#Multi value: When any variable yield more than on result #Syntax: Occurs when we remove any object from report that is used in the formula of nay variable.#Error: Generic Error#Incompatible, Context Error: Generally occurred when wecontext is not properly defined for calculation and when wetry to place two incompatible objects in one table.

#Div: Divide by Zero49. How to Shedule the reports in Xi R2You could see the option of scheduling in infoview,right below your report...otherwise u cud schedule it fromCentral management Console50. Explain about the different between 6.5 & Xi R2B.O 6.5:-- > 3tier architecture > Rep created after theinstallation > In Webi wise :-- > There is no alerters &There is no merge option> In 6.5 Contains 57 tables are there >


6/32

In security level wise also some changes are there :> in supervisor acess security servies option is there.>In 6.5 There is no Casading prompt.> Here separate Supervior & B.C.ABOXIR2 : Desiner wise-- > directly to restict data indesigner level. > New feautuer is Cascading prompt Webi wise : > here alerters & sub alerters also possible> Merge Option is also possible> BCA + Supervisor combined in CMC.>doc domain & uni domains are located in form of folders> here secured & Saved in folders & categories.> Sheduled directly in Webi.Architecture wise lot of difference is there between BO6.5 and BOXI.1. In BO6.5 we have to copy BO. main key in each system to install s/w.For BOXI no need of copying BO. main key.2. In Bo6.5 Supervisor control all the aspects. While in Bo xi Supervisor is replaced by CMC(Central management console) is take care under CMS (Central Management Service)3.6.5 is user centric and XI is object centric4. BO 6.5 is a 3 tier architecture Universe Domain, Document Domain & Security Domain. Whereas B.O. XI is 5 tier architecture with Client, Application, Intelligence, Processing and Data tiers.51. how to restrict null values in webi report?I believe you can define a formula like belowNot IsNull(object). This formula should bypass all recordsthat has null values..There might be some other ways too..52. how to do scheduling in desktop intelligence in BO XI R2 ?

To schedule a Report first you to export the report to theAdministrator and select the Folder then select the object and select schedule and you will get the choice to select like once, ondemand , weekly, monthly so on. if you stillconfusion then go through the Administrative Guide.Once the Report is saved, then click on file, go to Export,

and export the export which you want. Once the report isexported then a small dialog box appears which shows that Exporting is done successfully, then save ok. Now go toCrystal Enterprise (Infoview) and open the report which youexported earlier in Desktop Intelligence. Click on that folder and you can see the Report over there. Then fromthere we can schedule the report like, daily, hourly,

monthly, qtrly, yearly etc.......53. what is difference between folders and category ?folders: folders and subfolders are used to organize documentscategories: categories are a way to classify your informationfor example, you could place your financial reports anddocuments into a folder name finance and you could classifyor tag your reports that deal with specific financialmatters as payroll, accounts, payble and accounts receivable.54. Tell me about linked universe?a) Linked universes are universes that share common components such as parameters, classes,objects and joins. Among linked universes one universe is said to be kernel or master while theothers are the derived universes.b) If the data provided is from two different data providers then we can link those two universes.Such universes are called as linked universes.c) In real time scenario we will work with linked universe. here same data source and diff data source is not a issue. We can fetch max 15 to17 tables in single universe. More than that u will create another universe and link it.File-->parameters -linksd) Concept of linked universes is based on inheritance. You can specify your common classes andobjects in Parent universe (Kernel) and then link this universe in child universe (DerivedUniverse) to make use of these classes and objects. In Derived universe one can add their owntables, classes and objects.However linking universe does not link following...->Parameters->contexts->Aggregation55. How do you share the universe?By moving it as a file through the file server and exporting it to the repository56. How do you give security to universe?We can secure the universe by applying security restrictions through Universe Designer.


7/32

We can apply following types of security restrictions on different users:1. Object Restriction2. Row Level Restriction.3. Table Mapping.4. Connection Restriction57. What are zero client and thin client?Zero-client viewers do not require client-side software to be installed or downloaded. Insteadthese viewers display the reports as DHTML.Thin Client Viewers require components to be downloaded and installed on thecli ent scomputers. These client viewers offers better report fidelity but can require more administrativeoverhead

58. What is a Variable?a) Variables are used to prevent the same computation being performed several times as thevariable allows you to store the values so that they can be used later.b) A variable represents specific data or a value, and acts as a placeholder for that value. Unlike aconstant value, which is fixed and unchanging, a variable can be repeatedly assigned different values. You assign a value to a variable and the variable maintains the value until you later assigna new value. Because of this flexibility, it is necessary for you to declare variables before you usethem. Variables can be treated as a normal attribute, that is, it can be a source or target of atransform59.@prompt ('message', ['type'], [lov], [mono/multi], [free/constraint]) what isConstraint?Free Means, User can either enter value or select value from Lov.Constraint Means, Usercan t enter their value, they should select value from LOV60. What is a Micro cube?a) A cube contains data in multi dimensional analyzed format.Its components are:1) Measure / Fact: - It's an object which is been analyzed.2) Dimension: - It's an object with respect to which we perform Analysis.3) Detailed: - It's an object which provide extra information about a dimension.b) Micro Cube is a processing Unit. It is composed of facts & Dimensions & measures.Micro Cube is cleared by using "Purge" Option.61. How to Analyze Join problem and which method is the best to resolve that?Join problems are analyzed by Integrity checking and resolve by setting cardinalities62. Say, the query gets executed and we got the results. In case if we have a largenumber of rows, how can we know the exact no of rows returned?

a) From the data manager tab we can know the no of rows returned and the time taken to run thereport.b) Click on any column in result set, right click and select count all. This will display the totalnumber of columns in the result set.64. Is there any way to know how long the report executes and how many recordswill be returned before hitting the "run" option?a) Go to Definition tab in the data manager there u find these query options.b) Before run a report just click on view button u can see the report.c) Simple! Take the report query and modify to take the count in the query and execute it at theback end.65. There are 2 types of strategies are there?1. Built-in Strategy2. External Strategy.Can you please explain them in complete that what are these?Built-in Strategies:Designer provides a number of default strategies which we can use. These are strategies forextracting joins, detecting cardinalities, and creating default classes and objects. Options forindicating default strategies are located in the Database tab of the Options dialog box.External Strategies:We can also create our own strategies. Such strategies are referred to as external strategies.

With an external strategy, we can specify the exact way that objects and joins are to be extracted from the database structure. The strategywe use, for example, can be a script generated from a CASE Access tool. An external strategy is specific to one RDBMS.b) External Strategies are script files used how to read the data dictionary of source database.Data dictionary of source database having meta data information of tables, columns, views,synonyms, stored procedures etc.66. What is the difference b/w 6.5 & XiR2?


8/32

a) 1. XI R2 has a 5 tier architecture, where as 6.5 has 3 tier2. In XI R2 we have some new tools like Import wizard, conversion tool etc.3. In 6.5 we have a product called Business objects but now it is been renamed as Desktopintelligence.4. I n 6.5 we have supervisor, but there is no supervisor in XI and they have introduced the newconcept of CMC which is used to created users, user groups etc.5. In 6.5 reports are being stored in document domain of repository, now they have introducedthe concept of folders and categories.6. In 6.5 we have BCA (broad cast agent)to schedule the repots but in XI there is no BCA, u canschedule the reports using "Scheduler" in CMC7. Not only these even in designer, deski & webi, u have some new enhancementsWEBI:--In 6.5 there is no "Alerts", In Bo xi having "alerts & Sub Alerts" alsob) In Business Objects 6.5 Repositories are created by Supervisor after installing the software,Where as in BO XIR2 by default 3 repositories are created while installing the software.They are central management repository, File repository and Audit repository.67. How to connect to a server in a business objectsThere are some third party software are there to connect like "CITRIX"68. What are slowly changing dimensions & confirm dimensions?a) Slowly Changing Dimensions are basically those dimensions whose key value will remain staticbut description might change over the period of time. For example, the product id in acompanies, product line might remain the same, but the description might change from time totime, hence, product dimension is called slowly changing dimension.Where as confirmed dimensions are some thing, which can be shared by multiple Fact Tables ormultiple Data Marts.

b) Conformed Dimensions (CD): These dimensions are something that is built once in your modeland can be reused multiple times with different fact tables.For example, consider a model containing multiple fact tables, representing different data marts.Now look for a dimension that is common to these facts tables. In this example, let us considerthat the product dimension is common and hence can be reused by creating short cuts and joiningthe different fact tables.Some of the examples are time dimension, customer dimensions, product dimension.c) Confirm dimension:Confirm Dimension which is used to link more then 0ne fact table or data mart.For example In our project, we have created five data mart of different subject area ,our client requirements is to create a report by linkingall the data mart or subject area .To achieve that report we linked all the data mart through Person confirmed dimension .d) A confirmed Dimension (CD) is a dimension which is shared by different fact tables.

For examples, there are different data marts are there say Loans, Deposits, Withdrawals etc.....in this there is a dimension called Date which

is common to all. We can link to different data marts using a common dimension called Date in this example.e) Confirmed Dimension, it is a dimension linked with two or more fact tables.Suppose we have two fact tables like sales and production link with dimension product dimensionhere Product is the confirmed dimensionf) A dimension that carries the same meaning across the different fact tables is called conformeddimension. Confirmed dimension are a must to put a no. of data marts together to create aenterprise data warehouseg) In the schema a dimension which is shared by multiple fact table that dimension is calledconfirmed dimension.70. How do u migrate BO 6.x to XI?There are 2ways to migrate 6.5 to xi.1) Open migrate wizard. IMPORT WIZARD window appears. Import wizard is a tool to migratereports, Universes, Repository objects to one environment to other environment with in XI andalso from prior versions to XIR2 versions.2) While using this option, Report Conversion tool.71. Draw the architecture of traps?a)Fan trap:-Customers----->orders---->order linesb) Chasm trap:Reservation lineService sales->sales model72. What is the syntax for aggregate awareness?a) @ Aggregate _Aware (sum (agg_table_1), ... sum(agg_table_n))b) Aggregate awareness is a feature that makes use of predefined aggregate tables to enhance theperformance of SQL transactions. It is used to improve the speed by which aggregates are


9/32

calculated in the database. To set up aggregate awareness in a universe, you define or moreobjects using the @ Aggregate_Aware function. The syntax for this function is as follows:@Aggregate_Aware (aggregate_table_1, ... aggregate_table_n)c) The arguments of this function are all the names of alternative aggregate tables. When youformulate the syntax, you should be aware of the order of the arguments.The precedence is from left to right; this means that Business Objects determines the aggregate touse beginning from the leftmost argument.73. What is the Computation error? How to solve it?The computation error is related to the misuse of context operators in formula74. An index has been done on the primary key of a table. An update operation was

performed on that table. Now my question is1> what about the performance? Means faster or slower due to indexing?2> does the operation affect to the primary key constraint?

With an external strategy, we can specify the exact way that objects and joins are to be extracted from the database structure. The strategywe use, for example, can be a script generated from a CASE Access tool. An external strategy is specific to one RDBMS.b) External Strategies are script files used how to read the data dictionary of source database.Data dictionary of source database having meta data information of tables, columns, views,synonyms, stored procedures etc.66.

In this example, let us considerthat the product dimension is common and hence can be reused by creating short cuts and joiningthe different fact tables.Some of the examples are time dimension, customer dimensions, product dimension.c) Confirm dimension:Confirm Dimension which is used to link more then 0ne fact table or data mart.For example In our project, we have created five data mart of different subject area ,our client requirements is to create a report by linkingall the data mart or subject area .To achieve that report we linked all the data mart through Person confirmed dimension .d) A confirmed Dimension (CD) is a dimension which is shared by different fact tables.

For examples, there are different data marts are there say Loans, Deposits, Withdrawals etc.....in this there is a dimension called Date whichis common to all. We can link to different data marts using a common dimension called Date in this example.e) Confirmed Dimension, it is a dimension linked with two or more fact tables.Suppose we have two fact tables like sales and production link with dimension product dimensionhere Product is the confirmed dimensionf) A dimension that carries the same meaning across the different fact tables is called conformeddimension. Confirmed dimension are a must to put a no. of data marts together to create aenterprise data warehouseg) In the schema a dimension which is shared by multiple fact table that dimension is called

confirmed dimension.70. How do u migrate BO 6.x to XI?There are 2ways to migrate 6.5 to xi.1) Open migrate wizard. IMPORT WIZARD window appears. Import wizard is a tool to migratereports, Universes, Repository objects to one environment to other environment with in XI andalso from prior versions to XIR2 versions.2) While using this option, Report Conversion tool.71. Draw the architecture of traps?a)Fan trap:-Customers----->orders---->order linesb) Chasm trap:Reservation lineService sales->sales model72. What is the syntax for aggregate awareness?a) @ Aggregate _Aware (sum (agg_table_1), ... sum(agg_table_n))b) Aggregate awareness is a feature that makes use of predefined aggregate tables to enhance theperformance of SQL transactions. It is used to improve the speed by which aggregates arecalculated in the database. To set up aggregate awareness in a universe, you define or moreobjects using the @ Aggregate_Aware function. The syntax for this function is as follows:@Aggregate_Aware (aggregate_table_1, ... aggregate_table_n)c) The arguments of this function are all the names of alternative aggregate tables. When youformulate the syntax, you should be aware of the order of the arguments.

The precedence is from left to right; this means that Business Objects determines the aggregate touse beginning from the leftmost argument.73. What is the Computation error? How to solve it?The computation error is related to the misuse of context operators in formula74. An index has been done on the primary key of a table. An update operation was

performed on that table. Now my question is1> what about the performance? Means faster or slower due to indexing?2> does the operation affect to the primary key constraint?

88. When and where we use @variable function?The @Variable function is used to call the value assigned to variables.The variables are of two types:1) Business Objects system variables2) Personal text files variables

89. What is static filter and dynamic filter?In Static filter, record set is filtered based on a table field value.In Dynamic filter, record set is filtered based on the value specified for a specific business object property.90. What is report tracing in BO?Mainly the tracing concept is coming in designer level. Tracing means if you have 2 tables, if youselect one table column drag the cursor to the next table column, at that time cursor will turnsinto pencil symbol.91. How many micro cubes can a report have?Only one92. What is a local filter?A local filter is applicable only to a particular block i.e. the block on which it is created like on aparticular table or cross tab.93. Generally how do we get information for creating universes and reports?94. What is the difference b/w b.o. 5.1 or 6.5 or Xir2?BO 5.1.2 had no Infoview. BO 6.5.1 included Infoview, but no Crystal Report, CMC not present.Instead supervisor (thick client) was used for giving Users rights.BO XI includes integration with Crystal Reports, CMC (thin Client) for managing Users, securityand Profiles2) Oracle 9i includes Bulk Inserts, Index Rename and Table Rename.3) SQL is a 4 GL (Generation Language). Pl/SQL is a 3 GL.95. What is a Prompt?Prompts are used for asking the user for Dynamic Inputs while refreshing the Report.96. Can we create reports without creating Universe?Yes we can create reports without creating Universe.97.What are ad-hoc reports?Ad-hoc reports means with in the organization user can create reports by directly interact with ITpeoples. That is time depended reports not detailed reports.


11/32

98. How to link one location universe to other location universea) Click on File menu---> Parameter---> Links---->Add Link and then choose the universe youwant to link and give ok. Then the universe is added to the existing one.b) In Designer, we can't join two universes, we can link two universes.1. Click on the File menu; say Parameters then one dialogue box is displayed.2. Click on the Links tab, and say Add Link then choose the universe u want to link and say ok.Then your universe is added to the existing one.99. What is maintaining universes? a) Maintenance of universe means adding new tables, refreshing the table structure after addingnew tables, create the joins between the new tables to existing tables identify loops if any,

examine the integrity checks after any changes, determining the cardinality if any, resolving theloops. Adding the new objects and classes, exporting, restricting access to users etc..b) All the operations after the initial production phase are called maintenance of universe.We have to add some more tables to schema design as per client requirements and finding anyerrors after adding the tables. If at all any resolving them and generating reports.10o. How to hide the tables in webi?We can hide a table in webI when the table is empty.From the properties tab, deselect 'Show when empty' check box.101. How do u get requirement from the client?Design Specification (.doc) -

Shows the architecture of the Project.Requirement Specification (.doc) - Security Requirements, Performance Requirements, NonFunctional Requirements, Functional RequirementsProject Plan (.mpp) - Project DurationReport Specification Template (.xls) - Look and feel of the ReportsData Element Matrix (.xls)- Tables and Columns involved in this Project.102. How do u Receive requirements from the client?Through web intelligence and through browser103. What is Scope of Analysis?a) Using this Scope of Analysis we know up to what extent we can drill the Report b) Scope of Analysis determines the additional objects to be included in the query so that the datawill be available in drill mode. Before you can drill, you must use Scope of Analysis to select theobjects to be retrieved in addition to those that were placed in the Result Objects.c) Scope of analysis: it let's u add more data to the micro cube from hierarchies. This data is usedfor multidimensional analysis. When you add the data to the micro cube, the added data is not initially displayed in the report. When you drill the data it displays the added data for the purposeof multidimensional analysis. The scope of analysis button is located in the query panel.Here we just specifying the path for objects to get the detailed or summarized information using

drill option for analyzing the data in different ways104. HOW TO EXPLAIN SHORT CUT JOIN AND THETA JOIN?a) Shortcut join: it is direct join between source and destinationExample: country-->region-> cityWe can connect country and city using shortcut joinTheta join: non equality condition between two tables.b) Short cut Join providing an alternative path between two tables. passing intermediate tables,leading to the same result, regardless of direction. Optimizes query time by cutting long join pathsas short as possible.Theta join Link tables based on a relationship other than equality between two columns.105. WHAT ARE THE TYPES OF UNIVERSES? PLZ EXPLAIN IT?Universes are two types1) Simple Universe and2) Complex Universeb) Derived Universe, Linked Universe and Core Universe are the Types of Universe.Simple and complex (linked universe)

106. What are the types of Connections?1) Shared: Available to multiple users2) Personal: Belongs to user, who created it, others cannot use it.3) Secured: These are centralized and any one can use it and used to deploy business objectsreports107. What is meant by slowly changing dimensions?Master data occur in the OLTP system and that can't change regularly, when the changes areoccurred in the OLTP system, that changes can be handled by the dimension tables. Such type of dimensions is called slowly changing dimensions.There are three types of dimensionsTYPE1 (Maintain only current data)


12/32

TYPE2 (Maintain complete historic data)TYPE3 (Maintain one time historic data)108. What is meant by scorecards?Provide fast and effective way of monitoring key measures.Scorecard is a concept used for measuring a company's activities in terms of its vision andstrategies, to give managers a comprehensive view of the performance of the business.109. Case1: A person buy a car, case2: rent a car which is context & which is alias?Why?Buy a car is context & rent a car is aliasBecause, buy a car is a fact & rent a car is a look up, alias is created on look up tables.110. What is meant by Ad hoc reports? Can any body will explain with examples.Ad hoc reporting is a user friendly feature designed for all levels of users. Custom reports arecreated using queries.b) Ad hoc meant for management users. Example BO is ad hoc reporting tool used to make quick decisions.Example: if you have a one shopping mall u want find out the stock status. For clearance of thestock u need to take a decision what type of decision u need to take for clearance of stock.111. What is a Query?A query is one or more statements that request data from a database. If the data is available, thenthe requested data returns in the form of a table which contains rows and columns. Queries aresent to the databases in a language called SQL. However, when using the Report Panel, SQLknowledge is not required.112. Explain about surrogate key?a) A surrogate key is an automatic system generated unique key.b) An artificial key which can be used to remove redundancy.

c) Surrogate key is a system generated key which is defined at database level to avoid theduplication of records. itdo esn t maintain any relations b/w tables like as primary key and it onlyallows unique data there is a command with sequence in oracle.d) A surrogate key is a substitution for the natural primary key. It is just a unique identifier foreach row that can be used for the primary key to the table.e) Surrogate Key is unique identifier Key in Production System, to avoid data duplication andredundancy in DWH

f) In a current database, the surrogate key is the primary key, generated by the database management system and not derived from anyapplication data in the database. The only significance of the surrogate key is to act as the primary key.113. What is the difference between sub-query & co-related sub query?a) A sub query is executed once for the parent statement whereas the correlated sub query isexecuted once for each row of the parent query.

Select deptno, ename, sal from emp awhere sal = (select max(sal) from empwhere deptno = a.deptno)order by deptnob) Nesting of queries, one within another is termed as a Sub-Query.114. What is the necessity of oracle for business objects, why the interview panel isconcentrating on oracle very much? Just we need the commands using select, joins?Why they r asking about cursors, triggers etc.What ever we do in the BO it needs to connect to Oracle with the help of queries. As myexperience says,it s some times necessary to have the derived tables to be created which needsSQL knowledge, to do data validation we need SQL queries. Actually for any BO Developeroptimum level of SQL knowledge is necessary. Because In BO we are mostly using oracle is asdatabase. So what ever you are selecting in the query panel it is fired on the database in the formof query. All of us know it is done by designer automatically. But in some scenarios we have toimplement freehand SQL queries, derived tables to get our target results and some times we haveto validate the background SQL generated by BO to understand how results are coming in. And increation of formulas and variables we need SQL knowledge.(to_char, to_date, trim, decode, sign, union, union all....). So SQL is must.Coming to the PL/SQL in some situations when the data is in huge amounts, normal sql not meet the required performance. So we have to use PL/SQL. So it is required in rare cases where you areuploading the data in the report automatically by running the UNIX batch or getting the hugeamount of data in to the reports. As per my knowledge in real time it is better to know about thewriting the procedures, creating the views are more enough. I think cursors, triggers etc are useddepend upon data needs.115. WHAT ARE TEMPLATES? EXPLAIN WHAT YOU HAVE CREATED?The different table templates you can use to display information on reports are:Vertical tablesHorizontal tablesCross tabs


13/32

Forms1) Vertical tables display header cells at the top of the table and the corresponding data incolumns.2) Horizontal tables display header cells at the left of the table and the corresponding data inrows.3) Cross tabs display values for dimensions across the top axis and on the left axis. The bodydisplays the values of a measure that correspond to the cross section of the dimensions.4) Forms are useful in your report if you want to display detailed information116. WHAT IS CARTESIAN PRODUCT?a) It is a situation in which a Query includes two or more tables that r not linked by join. If weexecute that query, it will retrieve all the possible combinations b/w tables that are not joined. Inthis situation condition is invalid or omitted completely, the result is Cartesian.c) A Cartesian product is defined as all possible combinations of rows in all tables.

d) A Cartesian product is a result set which contains all the possible combinations of each row ineach table included in a query. A Cartesian product is almost always an incorrect result.119. WHAT IS CARDINALITY?a) Cardinality is a property of a join that describes how many rows in one table match rows inanother table. Cardinality is expressed as the minimum and maximum number of rows in acolumn at one end of a join that have matching rows in the column at the other end of the join.b) Cardinality defines the numeric relationships between occurrences of the entities on either endof the relationship line.Eg:1)1:12)1: M3) M: 14) M: Mc) The minimum and the maximum number of row matches can be equal to 0, 1, or N.d) Cardinality is mentioning the relation ship between the two columns participating in a join...Eg: if cardinality is 1 to n...for every column value in first table's field there exists many columnvalues for the field in second table.Ex: For every customer there may exists more than one address(Permanent and temporary)120. HOW TO SAVE UNIVERSES AND DOCUMENTS IN THE REPOSITORY?a) When ever we save universe it directly gets saved in local repository. If we want to access theseuniverse from deski or webi then we will have to save these universe to central repository byEXPORTING it, it will directly be saved in default location in central repositoryb) By exporting the universes and documents, we can save them to the repository. We can alsopublish them to the central repository.

c) If u are working in client system u must save ur universe and files in server system repository.Process: 1st save the Universe.File-->export--121. Can a Universe be linked to more than one data source?a) The Various data source are:UniversePersonal data filesFree hand SQLVB proceduresStored proceduresOLAP serversb) Any number of data Source can be linked by linking common dimensionsFeatures of Dimension:The dimension objects do not have to have the same name(E.g. Person, Person Name)Only dimension objects can be linked (e.g. Person Name, Encounter Type, etc.)The dimension objects must have a common data format (e.g. character, numeric, etc.)Common values must be in the same case etc.c) Yes, we can link to more than one data source. We can have universe connection to more thanone data base. We can achieve this by creating the db link between two data bases and thenconnecting it to the universe to any of the db.

d) You can have a single database connection to a universe.e) Definitely it is not possible to use more than one database connection to a single universe.122. IS IT POSSIBLE TO CREATE REPORTS FROM DIFFERENT UNIVERSES INONE DOCUMENT?Yes, it is possible to use different universe to generate a single report....multiple data providers.123. TILL WHAT LEVEL OF SECURITY BO SUPPORTS?


14/32

a) In BO XI R2, the row level and object level. Security can be done in the universe itself.b) In Bo the security levels are applied to row level and column level. Both have been handled bythe administrator.In supervisor tool (or) in designer tool these two levels of securities are used to restrict the data at row level or column level in case of particular user or user group.124. What is Row level Security?The measure of specifying user can retrieve which rows of data based on a column of data orcombination of columns is called row level security.125. HOW TO SPOT A HIERARCHY?From the designer u can spot the already mentioned hierarchy and also u can change or edit thesame.Go to Tool->HierarchiesHere u can ether add a new one or can also edit the existing one.126. WHAT ALL DIFFERENT KIND OF FUNCTIONS AVAILABLE WHILEDESIGNING UNIVERSES?Some other function like Number, Character, Date functions &@ functions like, @Aggregate_Aware, @prompt, @select, @where, @script and @variable.All the Universe Parameters (6 tabs) available in the universe parameters window are veryimportant functions to create any universe.126. WHAT TYPE OF JOINS RETURNS INCORRECT RESULTS?Isolated joins, cross join, non equi join127. WHAT IS THE PURPOSE OF TESTING INTEGRITY OF THE UNIVERSE? a) To check the universe weather it is correct or in correct, meansthat any isolated joins, divergence, loops, contexts, wrong joins, parsing happened in the universe.b) An integrity check detects:1. Invalid syntax

2. Loops3. Isolated tables4. Isolated joins5. Loops with in contexts6. Missing and Invalid cardinalities.129. WHAT KIND OF TOOL BO Is?a) Bo is a reporting tool to Query the database or data warehouse.b) Bo is a query, reporting and analysis tool.c) Bo is an OLAP tool. (ROLAP)130. HOW DO YOU RESOLVE MULTIVALUE AND COMPUTATIONERROS?

#MULTIVALUE error can be resolved by putting the input context.#COMPUTATION error can be resolved by puting the reset

context in output context.Create a new variable(ex:test) and copy the formula of the old variable to this new one and assign the column to this new variable..is thesolution for multivalue error.Computation error: Use Max() function before the formula inthe report to resolve a computation error131. HOW YOU WORKED WITH MULTIPLE DATA SOURCES?IF YES ?HOW DOYOU LINK THEM?you can create different universe for different sources andlink them in BO.132. HOW DO YOU SCHEDULE THE REPORTS?we schedule reports using broadcaste agent.we have a simple procees to shedule thee reports.when usaved ur report in perticular folder.connect sever through browser tool go to ur folders andshedulein 6.5 we can use broad cost agent but in the case of boxi we can use boe .net launch padIn 6.x and previous versions, Broadcast Agent is used toschedule the reports.In XI and XI Release 2, any user who is authorised toschedule documents can schedule the reports.Broadcast Agent lets any authorized user schedule documentsto be refreshed on a regular basis. Scheduled documents maythen be automatically distributed to targeted individuals orgroups or published for all users to access. Users cancustomize the information they send by executing a standardreport and then bursting it so that recipients receive onlythe information they are entitled to by their security profile.133. GENARALLY WHAT ARE THE PROBLEMS ARE FACING WHILE CREATING


15/32

REPORTS?THE MOST COMMON PROBLEM IS JOIN PATH PROBLEMi.e,LOOPSCHASAM TRAPSFAN TRAPS134. GENARALLY HOW MANY UNIVERSES ARE CREATE FOR EACH PROJECTS?It's depends on the project requirement.There is no restriction on the creation of the universes.It's all depends on the project In general, One universe is sufficient for a project and if we need we can link other universe fromother projects...

this totally depend upon ur project requirement 135. i am using Business Objects 6.1(a) facing a problem. ie when we save report inxls format then in xls sheet pictures are inserted into rep file are not come. Is it abug.we can't save the report with chart in xls,text format.only save in html,.rep,pdf While saveing the report we have to save in the form of save asselect this format:-1)Microsoft Excel Sheet(.xls)2)HTML format(.htm)3).pdf you can select any one of them it is possible.136. Re: what is the diff between etl tool and olap toolETL tool is used to extract, Load and Transform the datafrom one system to another system. OLAP tool is a reportingtool which will generates the reports that are useful fordicison support for top level management ETL tool are nothing but OLTP tool whereas OLAP tools arereport net toolsETL(OLTP) are extracters tranfers and loaders typeOLAP tools are analysers137. WHERE DO YOU USE GLOBAL FILTERS ,EXPLAIN WITH EXAMPLE?gobal filter acts on all fields in the report table138. WHAT PROBLEMS ARE NOT KNOWN WHILE PERFORMING INTEGRITYCHECK?

We can't find traps i.e. chasm trap and fan trap. It can beidentified only by visualization.139. CAN A REPOSITORY CONTAINS REPORTS?yes repository contains reportsin bo 6.5 reports are stored as documents in repostoryin bo xi reports are stored as folders in cmcYes, Repository contains reports. In BOXI also reports arestored in repository (file repository). Those reports infolders are also stored in repository only.Yes, Repository contains reports.In BOXI also reports are stored in repository (filerepository).Those reports in folders are also stored in repository only.bo 6.5 rep contains 50 tables........bo xir2 contains 8 tables.....1 table is dedicated for documents(document domain).

these 8 tables r also called cms db(central management server)........Repository Database will not store the actuall report file,it has the pointer of the report.Yes, Repository contains reports. In BOXI also reports arestored in repository (file repository). we can save ourreports in folders(phsycal) and categories(logical)..theseare avilable only repository only140. WHO ARE THE USERS OF THE REPOSITORY?general supervisor creates repository and designer ,user(report devlepoer ) uses the repository...the documents are


16/32

stored in document domain...in fact the clients also usesthe repository while seeing the documentsGeneral Supervisor, Supervisor are the users of therepository. Since they are the owners of the repository theycan create the repository and modify it whenever they want.who is having user as well as admin rights to access therepository141. IF I WANT TO INSTALL BO ENTERPRISE PRODUCTS IN WINDOWS 2000PROFESSIONAL SERVER, WHAT SHOULD BE THE SYSTEM CONFIGURATION? P3 700MHz** 1 GB RAM 5 GB hard disk space for BusinessObjects Enterprise and 1.5 GB additional for Performance Management CD-ROM** Windows support is limited strictly to the 32-bit versions of Windows operating on either 32 or64-bit (x86)AMD/Intel chipsets. BusinessObjects Enterprise software forWindows is not warranted or supported for use on other chipsets.142. User name and password is saved by Business objects when we createrepository. and this username and password is saved in Table obj_m_actor table inrepository. The password in incrypted form. It is possible to Dycrypt That Password.Not possible.143. Can we edit BOMain.Key file to connect with other repository with samesupervisor user name and password. But Database is different.

Yes144. How you get the requirement from client?client gets the information. that information is not in theorder.they r unable to under stand info.it can not helpfull totake the decessions. then the clint meets the company.Clent first contacts the company's BusinessDevelopmentManager of the company, Then Meeting and a chat happens in a clients place or client coming to company, Thengets the requiement according to the deal144. what is prompt? Cascading prompt? Syntax

To prompt the values and it is used on where condtionand filter rowsyntax

@select(class\object )= @prompt ('message','type','{values1,values2...},class\object,mono\multi,free\constrained)it is nothin but a dialog boxit can used for to take the values.syntax:@prompt('message',['type'],[lov],[mono/multi],[free/constraint])Prompt: It is used to create an interactive object. andalso it is dynamic filter.General syntax:@prompt('message',['type'],[lov],[mono/multi],[free/constraint])In designer we can write this way,@select(class\object )= @prompt ('message','type','{values1,values2...},class\object,mono\multi,free\constrained)).Cascading Prompt: it is based on one prompt to anotherprompt. it is also refer to hirerchy also & designed in unilevel.IN BOXIR2 wise:--go tools --> click cascading lov --> edit lov windowopen --> write conditions how many prompts u want. -->click ok.145. what is drill down?Action of navagating thorough levels of data. by drill down youn can reach the more refined ordetailedinformation.analysing the data in different angles and levelsDrill down is a one of the concept in Drill.Drill is nothing but an action of navigating data thru


17/32

levels of data. Drill down - with the use of drill down youcan reach more detailed information.Navigating data to lower level in the hierarchy with in thecubemove from summary information to detailed data.Drilling thedata into end level of hierarchy146. what is slice & dice?slice and dice is to arrange the the data in differnt ways.it can chage as rows to columns and columns to rows.The ability to move between different combinations of

dimensions when viewing data with an OLAP browser.Multidimensional analysis tools organize the data in twoprimary ways: in multiple dimensions and in hierarchies.Slicing and dicing refers to the ability to combine and re-combine the dimensions to see different slices of theinformation. Picture slicing a three-dimensional cube of information, in order to see what values are contained inthe middle layer. Slicing and dicing a cube allows an end-user to do the same thing with multiple dimensions.147. what are the features in BO?define scope of analysis.define condiations.create master and detail reports.add formulas,local variables and functionsbreakeup tables and disply tha calculations.create charts.analyze the data in drill mode.use slice and dice.formate reports.export reports.most of the reporting tool had same features but bO is moresecure..can work with remotely using web I,with out installing of BO s/w in ur local system148. Why we are going to data warehouse?Data warehouse is used for to store the large volumes of data. It can be used for futureforecasting. It is the collection of key pieces of information that can be used for to take thedecision by the managers.The main aim of data warehouse is in analyzing the large

volumes of data so that it can be helpful in taking business decisionsfor reporting one day details also enough.but analysismeans we need comparision means we need some old data iscalled historical data.the data ware house saves historicaldata ,we con't to any data base manuplations.where is in normal databases we arte able to maintain someextent of data .after that for entering new data u need todelete the old data.BUT in Data ware house u are able to stote years of recordsno need to delete the old data149. what are the multidimensional analysesmultidimensional analyses that can be used to wide viewvarities of data or informationMultidimensional analysis is the analysis of dimensionobjects organized in meaningful hierarchies. A hierarchy isan ordered series of related dimensions.Multidimensional analysis allows you to observe data from

various viewpoints.Multidimensional analysis means analysing the data bylooking at various view points.In BO,In 2 ways we can do this.1.Slice and Dice2.Drilling.Multidimensional analysis is analyzing the data in different ways. There are two options are available in BO,1.Slice and Dice, it allows us to view data differently i.e.we can change the position of the rows to columns andcolumns to rows.


18/32

2.Drilling, using drilling option we can view data indifferent views i.e. we can know the level details of anydimension. Suppose if we take Date dimension, we can usedrill option to view the next level of detail i.e. from yearto quarter and from quarter to month and from month to day.150. What is data mart?datamart is nothing but a database. it can be stored dataabout the particular orginazation.A data mart is a particular subject oriented block of datain the datawarehouse in the business line like production,sales, marketing etc. they are two kinds of datamarts arethere one is independent & Dependent datamarts.sub set of datawarehouse is called data mart.A data mart is a subset of data warehouse that is designedfor a particular line of business such as sales, marketing,finance, etc.Data mart is of two types:1) Dependent data mart, in which data can be derived froman enterprise-wide data warehouse.2) Independent data mart, in which data can be collecteddirectly from sources.In the industry when a organisation goes for a enterprisewide Datawarehouse the cost involved in setting up . itsmaintenance and other overheads are also associated withit. So due to budget and time constraints some

organisations initially set up a Data Mart to facililtatethere immediate needs . These Data Marts are generally set up at department levels and in a future date if utilityarises then datamarts across the organisation can beintegrated and a full fledged data warehouse can be formed.In a way Data Mart is a subset of Data Warehouse.151. .what is conformed dimension? R u used?Confirmed Dimention is a dimention table which is connectedto the multiple fact tablesA dimension that is used in more than one cube.The use of conformed dimensions and shared measures is the

primary way a set of data marts can be united into oneconsolidated data warehouse.

conformed dimension table is once created that is not changed occutionallyA Confirmed Dimension (CD) is a dimension which is shared bydifferent fact tables.it is a dimention accept ble join relation between two facts152. what is LOV? where it is store?LOV is the list of values.it can retrive the data valuesassociated with the particular object.this can be stored in sub folder of USERDOCS with .lovextension.LoV is list of values it displays the list that contains thedata values associated with an object.A list of value can contain data from two types of datasources...1. Database file2. An External file.LOV is nothing but listy of values.as per require ment we can generate LOV for limited no of objects.we can save it in repository serverwe have cascadiding loV SALSO WE CAN GENERATE LOV S FORMULTIBLE OBJECTS AT A TIME153. What is repository? TypesIn XIR2 CMS Repository :Which consist of two database (System & Audit)Input file repository:Template of the report Output file repository: Instance of the report.repository is the set of data structers that can be storedin the database.repository is a oraganizing metadata or cenralizedmetadata


19/32

storage placereposirory is create new folder structuretypes:repository managerrepository admin consolerepository is a central store area between group of users.repository is avilable under cmsinput and output repositories154. what is alias?

one user prefrom different roles is called aliasegtwo dept are there sales , HRuser of sales working in HR with different row is calledalias.alias is logical popint to alternate to the table name.thiscan be used to resolve the loops.Aliases are references to existing tables in a schema. AnAlias is a table that is an exact duplicate of the originaltable with a different name. The data in the table isexactly the same as the original table. An alias breaks aloop by using the same table twice in the same query for adifferent purpose.An alias is a logical pointer to an alternate table name.Exact copy of the original table.Establish a one-one joinbetween the original table and the table which is aliased.The aggregatre results should be canned on to the aliasedtable and not the original table.alias is a logical table of existing look up table.usingalias we can resolve looops155. What is loop? How resolve the loop?explain it?a situation occures more than one path exists from one tableto another table.to reslove the loops we can use the allias ans context.if a loop contains only one lookup table then the loop canbe resolved by detecting the alias.if a loop is having 2 or more fact tables(multiple fact tables) then the loop can be resolved by detecting context.Loop can be resolved either alias/ context.

Loop is a Multiple paths between the tables selected inqueries. Or you can say loop is a closed path structure.Loops can be resolv ed byALIASESAlias - Same as the namesake in SQL.Exact duplicate of the original table. .A different name tricks the SQL query to accept that you are using 2 different tables.CONTEXTSRule which helps BO decide which of the 2 paths to choose in a loop.BO prompts the user to indicate the correct perspective(relevant path) for the query.When to AliasA loop with a single lookup table should be resolved by an aliasA lookup table can be identified by its cardinalityA lookup table only has the one end of joins attached to it If your universe is simple in terms of tables then go for

alias.If your universe is complex in terms of tables then go forContext.Alias entails the propogation of the universe.Contexts are not liked by the enduser because we areforcing the enduser to the database which is the against tothe universe basic rule ie to keep the endusers away fromthe database.

loop is nothing but a continuous data flow .it is a pipeline.it is a close path end to end..using alias table wecan resolve loop sA loop is a set of joins that defines a closed path througha set of tables in aschema. Loops occur when joins form multiple paths betweenlookup tables.156. what is context? How u create? With example.it is a set of joins that specefies one of several pathsthrough tables in loop.if a loop is having 2 or more fact tables(multiple fact tables) then the loop can be resolved by detecting context tools-->insert context thenyou can select the path.157. How can we improve performance?By making use of Aggregate tables.1)usinf aggregated tables2)using shortcut joins3)removing unwanted classes and objects4)removing unwanted joins5)lov should be based on smaller look up tables158. What is the use of BO SDK?Bo SDK main use is to suppress ?no data to fetch? usingMacros.

The BusinessObjects Enterprise SDK allows you to build webapplications that interface directly with yourBusinessObjects Enterprise system.BO SBK Means, BO Software Development Kit.It Used for BO With Java or BO With Dot Net Integration.You can integrate BO in java or .Net application.It provide Java & .Net Api classes & functions.159. What are the general issues in migration process?Alignment, performance.Before Migration, one should have a thorough with1. Import Wizard2. Report Conversion Tool - for converting the DeskIReports to WebI Reports

Issues can be:1. What type of Migration u want to Use-a) Single Passb) Incremental Migration2. Importing Security or not.3. Repository Migartion- such asa) Merging Multiple repository into oneb) Moving one to Multiple Repository (Depends on therequirement)4. Need to take care of Versions and Platforms - Supporteddatabases,Web and Application Servers, Web Browsers andOperating Systems.5. User/Group Migration6. Setting up Folders/Groups Structures.7. Document Migartion.8. Taking Backups9. Setting Up Servers etc.There are lot other issues also.1)Formatting issues1)Linking Universes1)hiding of variables you cant do it in xi r2160. Why do we need metrics and sets?Metrics are used for analysis and Sets are used for grouping.161. what is the source for metrics?measure objects.162. What is the use of AFD? Where it can be stored?used to create dashboards. It can be stored in repository,corporate or personal.163. What is a Set?


21/32

Its nothing but grouping of users.164. What is metrics?Metrics are a system of parameters or ways of quantitativeand periodic assessment of a process that is to bemeasured. These are used to track trends, productivity.165. What is the difference between master-detail and Breaks?In break common fields are deleted whereas in master-detail , we declare certain entity as a master to get thedetailed information or report in this case the tableformat is changed.In Section(Master Detail) you can have two or moredifferent crosstabs or tables(hori/fin) eg. orders,customer, products etcWhere as In break one block is break into groups andsubtotal is shown eg customer can be broken intocountry/state/city

In Section(Master Detail) you can have charts for eachsection or detail. can have chart and table combination aswell.Whereas in Breaks u cannot inseart a chart for each of thegroups formed out of break 166. What are Alerter, Filters, Breaks and Conditions?Alters are nothing but they are used to draw attention to ablock of data by highlighting.Breaks are nothing but grouping the data without any changein the format.Condition is used to retrieve data which meets certaincriteria. Filters are used to get necessary data.Alterters are conditional tests.Conditions restict the data at the database level.Filters restrict the data at the report level.Breaks can be used to remove redundat data and the dataremains with in the cell content.167. What is a join? Explain different types of joins?Join is used to link to tables depending upon the datarequested by the user, Usually we have Inner Join, OuterJoin, Left Join, Right Join, Full Outer join.Combining a data from multiple tables is called join.

There r 5 types of joins r there.1)Simple join 2)Equi join 3)Outer join 4)Theta join5)Short cut joinA join is a condition that links the data in seperate but

related tables. The tables usually have a parent-childrelationship. If a query does not contain a join, thedatabase returns a result set that contains all possiblecombinations of the rows in the query tables.Types of joins:1) Equi-JoinsLink tables based on the equality between the values in thecolumn of one table and the values in the column of another.2) Theta JoinsLink tables based on a relationship other than equalitybetween two columns.3) Outer Joins (Left Outer, Right Outer, Full Outer)Link two tables, one of which has rows that do not matchthose in the common column of the other table.4) Shortcut JoinsJoin providing an alternative path between two tables,bypassing intermediate tables, leading to the same result,regardless of direction. Optimizes query time by cuttinglong join paths as short as possible.

5) Self restricting joinsSingle table join used to set a restriction on the table.join is very imp concept in BOrelation between two tables is called joins.


22/32

we have 4 types of join relations 1:m,m:1,m:m,1:1types of joins in BO1)equi join2)theta join3)outer join(left/right)4)isolated join5)short cut join168. What is a loop? How can we overcome?loop is a closed path between end to end.continuous floe of data.creation of alias table is solution to resolve loopsLoop is nothing but a closed circular flow; it can beovercome by making use of Alias and Context.A loop is a set of joins that defines a closed path througha set of tables in a schema. Loops occur when joins formmultiple paths between lookup tables.Loops can be solved by using aliases or contexts.loop is a closed path between end to end.continuous floe of data.creation of alias table is solution to resolve loops169. What is the size of data base?In general it will be anything between 4-8 Terabytes.170. What do you mean by Object qualification?Object qualification represents what kind of object isthat, usually we have three types of object qualifiers theyare measure, dimension, detailed.Object qualification is nothing but a property of an object

determines how it can be used in multidimensional analysis.For the purpose of multidimensional analysis objects can be qualified as dimension, detailed andmeasure171. What is a category?we can store logical report here.in real time we can usecategories only.we can't manuplate the categories report It is nothing but grouping of certain entities.Categories tag objects in a meaningful way to provide anadditional method of classification, which makes searchingfor content easier for users. A Report in one Folder mayassigned to several Categories.Types of Categories:

1)Corporate Categories Created by admin or users who has

admin rights.2)Personal Categories Created by each user to organizetheir own personal documents.172. How do you restrict access to rows of a database?In XI version it can be done by using row-level security indesigner module whereas in 5i/6i it is done by supervisor.173. Can we have multiple domains?Yes.we have multiple domains,but security domain is not multiple,only document domain and universe domain ismultiple.174. When is the Repository created?In 5i/6i versions after installing the software, whereas inXi version a repository is created at the time of installation.175. What is domain? How many are there in a basic setup? What are they?Domain is nothing but logical grouping of system tables,There are three domains usually in a basic setup, They areSecure, Universe, Document.Business objects are sometimes called domain objects , anda domain model represents the set of domain objects and therelationships between them.176. What is BO Main. Key?BoMain.Key file contains the information about therepository site i.e it contains the address of therepository security domain.The General supervisor username n password is stored inbomain.key file


23/32

BOMain.key file contains the address of the repository'ssecurity domain. This key file should be distributed to allthe users of BO to work with BO or will access the borepository to share universes and documents. It is stored inBusinessObjects/LOCData folder.177. How to create Generic TIME CLASS, which includes Objects Year,Month andQtr?year=to_date(to_char(timeclass,'yyyy'));month-->to_date(to_char(timeclass,'month'));178. How to link two different universes ?go to universe parameters and select link tab and thenselect the universe.Universes can be linked using Universe Parameters. You canlink universes with any of the following approaches:1)Kernel approach2)Master approach3)Component approach

With the Kernel approach, one universe contains the corecomponents. The derived universes that you create from thiskernel universe contain these core components as well astheir own specific components. Any changes you make to thekernel universe are automatically reflected in the corecomponents of all the derived universes.The Master approach is another way of organizing the commoncomponents of linked universes. The master universe holdsall possible components. In the universes derived from themaster, certain components are hidden depending on theirrelevance to the target users of the derived universe. Thecomponents visible in the derived universes are always asubset of the master universe. There are no new componentsadded specific to the derived universe. Any changes youmake to the master universe are automatically reflected inthe core components of all the derived universes.The Component approach is merging two or more universesinto one universe.we have a concept in BO linked universe there we can klink multiple universes.file--.parameters-->links

179. How to Implement the the Built-in Strategy Script in BO Designer?strategy is used to extract structural information about thetables, joins ...bo has 2 strategy1. built-in -strategy2. external- strategy180. What are the security level used in BO?they r four1.hidden2.disable3.inhernt 4.enableSecurity Levels in BO XI are:1) Predefined2) AdvancedPredifined:1) No Access2) View3) Schedule4) View on Demand5) Full controlWith Advanced you can explicitly define the security level.181. What is slicing and dicing in business objects?slice & dice is used to analyse the data in different views& perspectives

Slice and Dice can be applied to rotate a microcube inorder to view it from different perspectives.


24/32

A microcube is a conceptual way to present the datareturned by a query before it is projected onto a report.You can choose all, or only some of the data held in themicrocube to create a report.slicing means it slices the cube based on a dimensiondicing means rotates the cube with independent of dimension182. How will you know the version of Bo using designer?in designe select the file tab,then click on parameter tabin that select summary tab then we will get the informationby emamWhile opening the designer,a BO patents page appear whichshows the version of BO183. Which command using Query Analyzer will give you the version of SQL serverand operating system ?select @@version184. How can we acheive Correlated sub-query in Designer?A correlated subquery is a SELECT statement nested insideanother T-SQL statement, which contains a reference to oneor more columns in the outer query. Therefore, thecorrelated subquery can be said to be dependent on theouter query. This is the main difference between acorrelated subquery and just a plain subquery. A plainsubquery is not dependent on the outer query, can be runindependently of the outer query, and will return a result set. A correlated subquery, since it is dependent on the

outer query will return a syntax errors if it is run byitself.185. Explain in Detail about Measure Objects? and what is the use of it? How tocreate it?It can be derived fro the Aggregate function.it convay thenumeric information by Dimesion object can be measured.Measure objects retrieve numeric data, or data that is theresult of calculations on data in the database.For example: No. of students in the Students Universe.Measure Object convey numeric information which is used toquantify a dimension object. A measure object returnsnumeric information.You can create a measure object by using aggregatefunctions such as,1)Sum2)Count 3)Average4)Minimum5)Maximum

Measure objects retrieve numeric data, or data that is theresult of calculations on data in the database.For example: No. of students in the Students Universe.It can be derived fro the Aggregate function.it convay thenumeric information by Dimesion object can be meassured186. What is the local filter and global filter in bo's?To hide & display the data.Local Filter is to single block to which it is created, but a global filter is to all the blocks which consists of that columna report can contain more than one block...same waya document can contain more than one report.....so if we see one report we have some blocks....applying a report filter to only one block is local filter..applying a report filter to all blocks is global filter...in any report.Global Filter will affect whole Report But local filterwill affect selected both only.187. What are the steps to taken care to improve the Report performance?The Report Performance can be improved by the followingperformance Requirements :1- The Report should open within 10-15 Minutes2- The data should be available within 24 hours ForExample - If there is some data error , it has to be takenin ETL ( Extraction , Transformation , Loading ). When the


25/32

mapping got refreshed , the data should be fetched into theReports within 24 hoursAs part of universe parameters increase the array fetchsize and try to use aggregate awareness.188. How toconnect one to one report?You can link thru Hyperlink optionBy using drill down functionality additional components will be added in HTML Tag.189. What is the drill up , drill down, drill by , drill trough ?drill-down means analysing the in different levels going tothe down let us eg as year--->quarter,quarte---> month andso ondrill-up means analysing the in different levels going tothe up let us eg as month--->quarter,quarte---> year andso on190. How to create Universe using Flat file in BO6.0If i am not wrong u can't create universe from a flat filebut u can generate a report from a flat file.choose "personal data files" in the new report wizardinstead of univese and input the file information.

191. What is the test methodology for testing BO Universes?Integrity Check is the option through which one can test the universse in BO.192. How can you access your repository with different user profiles?first thing we are under the member(user) of therepository.and we need to rights to access repository.we also need to create perticular user name and pass193. What is pragma?A PRAGMA statement appears in a PL/SQL block. It is not anexecutable statement, but it provides instructions to thecompiler194. Can we take report on Excel in Business Objects?yes. The businessobjects separately provided the option of get the report data from universe or others(personal dataoption)in the business objects entered wizard. Click orSelect the others option and it will let u different filesor extension files. here select .xls file and follow normalreport style.Yes, When u get the output of report then use save as .XLS

option.s sure,when we save the perticular report we have a optionto save in .XLsYes, We can take a report on excel in Business Objects,Process.. ..In Desktop Intelligence -> File -> New - Generate astandard report -> Begin -> Other -> Personal Data Files ->Finish -> format -> xls & select excel file from browseoption -> If excel file first row contains column name thenselect the check box -> First row contains column names ->Run.------------------------------------------------------------If you want to save a BO report in excel format then,After generating a report file -> save -> File name ->. .. ... . & save as type -> xls -> Save195. What is batch processing in Business Objects?batch processing means scheduling the reports196. What are different types of saving options in web intelligence?we can save as excel, RTF and .repPDF and html alsoThe saving formats with web intelligence are excel, pdf, csv and csv with options. Not possible with rtf, rep and html.

The saving options with webi are:1) excel2) pdf 3) csv4) csv with options(Not possible with rtf, rep and html)


26/32

we can see save the report as excel...webi....adobeacrobat....thats all ...no rep... rtf...etc.we can save webintelligence documents in two ways1.excel2.pdf only197. What are alertors in Business Objects? Alerts are set of instructions and rules to highlight output of reports.Alerters are conditional tests which can be used tohighlight the critical data.we can apply a maximum of 10 alerters on a singledimension/column and a max of 30 alerters on a report.198. What services the broadcast agent offers on the server side?We can monitor the Scheduled Reports are controlled in theserver side.We can resume or cancel the reports running in the Broadcast Agent.199. In Business Objects 4.1 version what is the alternative name for broadcast agent?Document agent server200. What are steps to be taken care to create a good Universe?A Universe is a business-oriented mapping of the datastructure found in databases: tables, columns, joins, etc.A Universe is a semantic layer between Database and endusers.A Universe can represent any specific application,system, or group of users. For example, a universe can

relate to a department in a company such as marketing oraccounting.A Universe can also pertain to a section within adepartment or just about any set of organized proceduressuch as a payroll or inventory system.A Universe consists of a set of objects, grouped by classes.Steps to be taken care to create :Prepare : Know the data sourceAnalyze :Identify the needs of the end user populationPlan : Design the universe(s)Implement : Create the universe(s)

Test : Using a test team (including end users) Deploy : Distrib
