Ex:- Tally, Ms Office- It is a Software which is ready to use with out any customization.

- Aplications :-----------------Ex:- SAP BW- It is a softeware which is customized as per the Client\User requirements.

Application :- PL + DB + OS + CONCEPT-------------------------------------

PL - To Design the Front End and Application LogicDB - To Design the BackendOS - It acts an InterfaceConcept - Billing of Super markets

2 types of Applications:-------------------------1) OLTP (Online Transaction Processing)2) OLAP (Online Analytical Processing)================================================

what do you mean by Business/Business Process/ System?-----------------------------------------------------

- set of Business Activities / Transaction ----------------------------------When 2 or more parties (Entities) interacting with each other, Perform a

Transactions like (Buying, Selling)

What do you mean by Business/Business Process/System ?----------------------------------------------------

- Set of Business Activities / Transactions (S/B)?-------------------------------------------------- When 2 or more parties(Entity) interact with each in the Business

, They generate a Transaction.--------------------------------------------------- Entity?

Any object which can perform work by itself or which we can use it to perform some work.---------------------------------------------------

" Exsitance of Entity is not the Business, These entities should interact with each other to generate the transactions and set of these transactions is Business"

- Master Data:- Detailed information about the Entities- Transaction data:- Data Representing a Transaction

- Transaction Data is generated when ever we have a transaction performed in the business

Entity: (Noun)------Any object which can perform work by itself or which we can use it to perform some work.

[* Existance of entity is not the Business, These entities should interact witheach other, to perform transactions and Set of the these Transactions is "Business" ]

Master Data:-

-------------Detailed Information about an Entity (Stronger Entity or Attribute of Stronger Entity)

Transaction Data:-------------------Data representing particular Transaction.

OLTP:-------* Online Transaction Processing* In OLTP applications, when ever we perform a transaction, we record the transaction into the Database and if there is a change in the transaction, we have to

change the transaction in the database. we can even select the transactions from the database and show the same data as a Report.* In OLTP applications, Transaction data is generated.

Ex:- Billing Application in Super market, SAP R/3, Railway Reservation Application, Banking Application, Hospital Management Application .

OLAP:------* Online Analytical Processing


4/33

* As part of OLAP tool, we extract all the Transaction data from different hetertogeneous OLTP sytems into OLAP and stag the Data and provide Analytical reports (Analytical Data)* Analytical Data - Data which can be used for analysis.* TD + OLAP ==> AD

Ex:- SAP BW, Cognos

OLTP V/s OLAP or Why OLAP or Why SAP BW:----------------1. When we do Reporting in OLTP it degrades the Performance of OLTP System, So we extract all the transaction data from different OLTP Systems and store data in OLAP and provide Analytical Data.

2. In OLTP we dont store TD for Longer time, So in OLAP we store Historical Data fro 5 - 10 Yrs.

3. In OLAP we can Integrate/Consolidate the data coming from different OLTP Systems in OLAP.

4. In OLAP we can provide authorizations based on the Data, But in OLTP we provide authorizations based on the reports/Transactions. because of this if we do reporting in OLTP system it affects ROI(Return on Investment).

5. In OLAP we can have more Analytical reports like one of the Top customer didnot buy one of your Top Product very easily.

****************************************************************

Basics of Database:---------------------* In any Database we store the data in a structure format called : Table.

* Table:---------* Set of rows and coloumns.

* Coloumns are used to define the properties or attributes of an object or Entity.* Coloumns will define the Logical Definetion of an Entity.

* Rows will define the physical existance of an entity.* Each row in a table is also called as Record.

* Every table must have a Primary Key.* We Use Primary Key to Uniquiely identify each and every record in a table.

* Every table will have 2 types of Coloumns- Key Coloumn (Part of Primary Key)- Non - Key Coloumn (Not part of Primary Key)

* All Non - Key Coloumns act as Attributes / Properties of a Key Colomn.

* Composite Key / Super Key:-----------------------------* When 2 or more coloumns of a table together act as the Primary key we call itas Composite Key / Super Key.

* De-Normalized Table:


5/33

----------------------When we store all the data in a single big table, and we find the data being stored redundently/Duplicatly,we call it as De-Normalized Table.

Dis - Advantages of De-Normalized Table:----------------------------------------1) Wasting Database Space2) Complexity will be high.

To overcome with these problems we spilit the De-Normalized Tables into multiple Smaller tables and these tables will be connected with the Primary Key and Foreign Key. The process of doing this we call it as "NORMALIZATION".

*Foreign Key:-------------* When a Primary of one Table takes part in the other table we call it as foreign Key.

****************************************************************

Data Warehousing:-----------------* W.H.Immon* Data Warehousing is an Concept.

* extracting Data from different heterogeneous OLTP applications and store the data and provide Analytical Reports for Decision Making Process.- The data what we extract should have the following Proper

ties:

1. T - Time Variant2. I - integrated3. N - Non - Volatile4. S - Subject Oriented

* Data Warehousing is a part of Business Intelligence.

Applications implementing the concept of DW:

--------------------------------------------1) Cognos - R2) Informatica - ETL tool (E)3) Data Stag - M (Staging)4) Oracle (EDW) - M (Staging)5) Business Objects - R6) SAP BW - is an End-to-End Data Warehousing Solution (E,M,R).

****************************************************************

Database Design in OLTP:--------------------------

* 2 dimensional* Normalized

* Entity Relationship Model---------------------------------------------How to Design ER Model?---------------------------------------------Step 1:---------Define the Business/Concept/Business Process/System:-


6/33

---------------------------------------------"XYZ Co is supermarket with 200 employess, having branches in different locations, we deal with different products,we have lot of customers generating the bills in different branhces."

Step 2:---------Identify the Entities in the Business:----------------------------------------- By using Noun Phrase approach.

1) employess2) branches3) Products4) Customer5) Bills

Step 3:---------Draw the Entity diagrams:--------------------------

Step 4:---------

Convert each entity diagram into a Table:-------------------------------------------Step 5:--------Form the Intersection Entity/table:------------------------------------Step 6:--------Normalize all the tables (Entity Tables and Intersection entity table ).6.1) Indentify the K.c and N.K.c of a table.6.2) Whether all N.K.c are dependent/related on the Primary Key or not.

* If N.K.C are not dependent on the Complete Primary Key then split theN.K.C into other table and connect Primary Key and Foreign Key.

6.3) Understand the Relationship between N.K.c and K.c and draw the entity relationship diagrams.* if N.K.C is related to K.c as 1:M then split the N.K.C into other tabl

e and connect with Primary Key and Foreign Key.* if N.K.C is related to K.c as 1:1 then store the N.K.C in the same tab

le.* if N.K.C is related to K.c as M:M then split the N.K.C into other tabl

e and connect with Primary Key and Foreign Key.---------------------------------------------Points to be noted:---------------------* Interscetion Entity:- Table which stores all the intersection data.* Stronger Entity :- are those which are directly connected to the Intersection

Entity.* Attributes of Stronger Entity:- Tables which are connected to the stronger entity.

ER Model:----------* Different entities(Tables) playing in the Business stored in different tablesconnected with PK and FK.* It will have Interscetion Entities, Stronger Entities,Attributes of Stronger Entities.


7/33

* ER model is Normalized.

****************************************************************Star Schema:-------------- ----> Star schema is an MDM ( Multi Dimensional Model ) which contains Fact table / Transaction data Table at the center, surrounded by Dimension tables / Master Data Tables existing withinthe Cube. ---->These Dimension Tables / Master Data Tables are linked to the Fact table / Transaction data table with Primary Key Foreign Key Relationship.

Limitations of Star Schema:------------------------------1) Master Data is not Reused, So master data is maintained Redundantly.2) Degraded performance.3) Limited Analysis.

****************************************************************Extended Star Schema:----------------------* Star Schema + SID technology ( Surrogate ID).* Fact table inside the cube connected to dimension tables and the dimension tables are connected to the SID tables which are connected to the Master data table

s.* Master data tables are outside the info cube.* Every master data table will have its own SID table.* When we load the master data, the system would generate the SID's in the SID table.* we have three types of master data : ATTR, TEXT, HIER.* Max. no of dimesion tables : 16* Max. no of keyfigures in the fact table : 233.* Max. no of characteristics can be assigned to 1 dimension : 248.* Fact table contains - Dimension ID's and Key figures.* Any information which is stored as the attribute of another charcteristic will always give the PRESENT TRUTH.* Any information what is stored inside the cube or referenced to the fact table

will always give the : FACT.* In order to design the optimized info cube we should always concentrate on reducing the dimension tables and at the same time reduce the number of records indimension table :-

STANDARDS:------------* If the master data tables are related as M:M, we assign them to different dimension tables.* If the master data tables are related as 1:M or 1 : 1, we should assign them to same dimension table.

- Star Schema:------------------

-Fact Table/Transaction data table at the center surrounded by Dimension tables/Master data tables connected with Primary Key - Foreign Key and all these tables existing inside the cube.

* Fact Table?-------------* any data what is stored in this table cannot be changed.

* Transaction data Table ?-------------------------* We store Transaction data in this table.

* Master data Tables ?----------------------* These tables store Master data(Detailed information about an entity).

* Dimension Tables ?

---------------------* Each Master data table is acting as a side of a cube.

* Transaction Data Table / Fact Table will have 2 types of Coloumns:-

a) Characteristics : on what basis we analyze a keyfigure.

b) Keyfigures : What we are Analyzing.

* Each Characteristics coloumn in the fact table/transaction data table will connect to one Dimension table/Master data Table.

- Fact TAble:---------------- 255- 6--------

- 249- 16-------233

- Dimension table:------------------------ 255- 6--------249- 1-------

248 - SID columns

- DIM ID's-------------- When we load transaction data to the Info Cube, DIM ID's are genersted based on the sid'S.

- CAn we load TD without MD?-----------------------------------Standard - Always load MD first and then load TD to improve loading performance.

- Standards to Design an Info Cube:----------------------------------------- 1. Whe we have 2 characteristcs related as M:M, we will have to assign to different dimensions.

- 2. Whe we have 2 characteristcs related as 1:M or 1:1, we will have to assignto same dimension.

- 3. Modelling a Key figure:--------------------------------


12/33

- If we Model the Keyfigure as an Attribute of a Characteristic - it gives Present Truth because the property of master data is Overwrite.

- If we Model the Key figure inside the Fact Table - it gives Fact, Beacuse theproperty of Cube is Additive.

- 4. Modelling a Characteristic:------------------------------------- If we Model a Characteristic as an Attribute of another charecteristuic - it gives Present truth, because the property of Master data is Overwrite.

- If we Model a Characteristc by connecting the SID table to a Dimension Table - It gives Fact, Beacuse the property of Info Cube is Additive.

Login Information:--------------------Client:---------* 000 and 066 - SAP Clients.* Active client is created by using a client copy of 000.* In SAP BW, we can only have one active client because of Client Independent tables (Integration).

- Info Area:--------------- we use this to organise the project.


14/33

- similar to Folder in Windows

- Info Object Catalogs:----------------------------- we use this to organise the project based on the type of Info object.

INFO OBJECTS------------* Info Object is the basic unit to build any structure(Info Cube,ATTR table,Text Table) in SAP BW.

* Info Object is Reusable to build any structure in SAP BW.

* Each Coloumn in a table in OLTP system is a Field.

* Each field in OLTP system will correspond to an Info Object in SAP BW.

Types of Info Objects:----------------------a) Characteristics------------------All Descriptive Data, which we use it to analyse the keyfigures.

Ex:- CNO,CREGIONB) Key Figures---------------ALL Quantitative measures, which we analyseEx- Price,Quantity,Revenue,Wages,Tax,Salaries,

c) Unit Characteristics-----------------------When we want Info Object to hold diff. Types of Currencies or diff. Types of Measures(UOM).* 2 Unit Characteristics given by SAP as part of Business Content - 0CURRENCY, 0UNIT

* If you want to create an Unit Characteristics it should be created with reference to either 0CURRENCY or 0UNIT.

d) Time Characteristics-----------------------When we want to store time factor informationex:- date,month,week,year,year/month* we cannot create Time Characteristics but we can only use the existing Time Characteristics delivered by SAP as part of Business Content.Ex:- 0calday,0calmonth,0time

- Info Objects:------------------ Characteristics - Business Subjects or Descriptive Matters

Creating Master Data Tables(ATTR/TEXT):----------------------------------------Step 1:--------Identify the no of Coloumns/Fields in the given Master data table in OLTP system

.Step 2:---------Out of the given fileds/coloumns, Identify what fields should be maintained in Master Data ATTR and what fileds should be maintaines Master data TEXT table.

Step 3:--------Create the Info Objects for all the fields required by the Master Data - ATTR table.

Step 4:-

---------Build the Master Data - ATTR table by using all these info objects ( YC_MATNO, YC_MATNM,YC_MATGRP,YK_MATPRC,YU_MATUOM).

Note :-------* we are supposed to build the Master Data - ATTR table for the info object corresponding to Primary Key field in the OLTP system.* /BI(C/0)/PXXXXXX

Step 5:---------Create the master data - Text table to store the S,M,L description.

Note :-------* /BI(C/0)/TXXXXXX* Importance of Language key Field in Text Table:- If we want to maintain the description in multiple languages, then we need to select the check box (Text language dependent) , then 'Langu key' field will be acting as part of primary key in the text table allowing us to maintain description in multiple languages.

Types of Connectors / Providers----------------------------------i) SAP Connection Automaticii) SAP Connection Manuallyiii) SAP MySelf Connectioniv) Flat File Connectionv) UD Connectvi) DB Connectvii) Connection by using BAPI's [ Business Application Programming Interface ].

*All the connection configurations are done by BASIS people.

When ever you maintain Connection b/w SSys and SAP BW.Configures Intermediate Documents [IDOC's]

We have two types of IDOC'si) Data IDOC's.---> carries records

ii) Info IDOC's. ----> How many records are get carried.When ever you work with external SourcesysMake sure whether the connection is OK or NOT.

InfoSource-------------Grouping of Logical related info objects in what way / what sequence thery are goin to communicate with the Source System****Infosource refers to Communication Structure.

We have 2 types of Infosourcesi) Flexible Update

ii) Direct Updatei) When ever our target is placed in INFOPROVIDER level we will go with Flexible Update. (eg: Infocube, ODS, Infoobject,.)ii) When ever our target is placed in INFOOBJECT level we will go with Direct Update. (eg: Infoobject)

* If the Infoobject is at Infoprovider level we have flexibility to generate reports on that Infoobject.* If the infoobject is at Infoobject level, we can't do reporting on that infoobject.

Data Source

--------------Grouping of Fields in what sequence they are comming from Source system.*Data source refers to Transfer Structure.

We have 4 types of Datasourcesi) ATTRii) TEXTiii) HIERiv) Transaction data

- Transfer Rules & Update rules:----------------------------------------- Transfer Rules:---------------------- Mapping Between Communication Structure & Transfer Structure.- We use Transfer rules to perform any kind of transformation to the data coming from Source.

- Types of Transfer Rules:-------------------------------1. Direct Mapping [Info Object]2. Constant3. Routine4. Formula

1. Direct Mapping [Info Object]:

--------------------------------------- Field --> Info Object

2. Constant:---------------- Fixed value for all the records

3. Formula:--------------

4. Routine:--------------

- Transfer Routine- TRAN_STRUCTURE

- TRAN_STRUCTURE-/BIC/ZCNO

- RESULT

/BIC/ZQTY/BIC/ZPRC

RESULT = .

/BIC/Y_PRC/BIC/Y_QTY

* Reference and Template------------------------


29/33

If we have an info object 'A', when we create the Info object 'B' by taking 'A'as the reference, all the properties of 'A' are copied towards 'B' and we cannot change any properties to 'B', We cannot load any data to the info object 'B' but it refers to the data / data dictionary tables of main info object 'A'.

If we have an info object 'A', when we create the Info object 'C' by taking 'A'as the Template, all the properties of 'A' are copied towards 'C' and we can change the properties of 'C', we can load the seperate master data for the info object 'C'.

When do we go with reference:-----------------------------When we want to create the new master data object which is supposed to hold thedata which is already a sub set of some other Master data objects, we go for creating the Master data object with reference.

Reference Example:------------------------- Sold to Party , Ship to Party, Bill to Party, Payer are created with reference to Customer.

- Sender Cost Center and Reciever Cost Center are created with reference to Cost Center.
