Who uses OWB 10gR2? Plan to? Wait and see?
Who uses Informatica/DTS/etc?
OWB 10g Release 2Codename: Paris
Overview
Context OWB and Metadata BI: Soup to Nuts Pre-Paris vs Paris Metadata User Defined Objects (Classes/Objects) Next Steps…
OWB 10g Release 2Codename: Paris
What is OWB?
Extract / Transform / Load (ETL) OWB is a CODE GENERATOR
PL/SQL, XPDL, CTL files
OWB 10g Release 2Codename: Paris
What is OWB?
=
OWB 10g Release 2Codename: Paris
OWB : Metadata
Metadata is central in OWB architecture A working solution requires one to:
1. Build ETL “logically”
2. Build PL/SQL from “design model”
3. Execute actual ETL (runtime) “Orphan” of data warehousing Operational and Contextual Benefits
OWB 10g Release 2Codename: Paris
Operational : Logic AND Code
BUSINESS LOGIC CAPTURED
OWB 10g Release 2Codename: Paris
Operational : Impact Analysis
What’s the possible impact of a change to the CATEGORY DATAFILE in my SALES application?
OWB 10g Release 2Codename: Paris
Contextual : Company XYZ
You have a Data Mart that produces “Sales” reports
BUT WHAT DOES IT MEAN!?!?
OWB 10g Release 2Codename: Paris
Contextual : Lineage
Does the SALES cube include data from the OE Schema?
OWB 10g Release 2Codename: Paris
BI : Soup to Nuts
Source (MVC) and DB / Extract Files Data Warehouse (staging/DW) Data Marts (star schema) Reports (configuration, calculations) Custom user and shared reports BPM Alerts, Dashboards, Closed-Loop
OWB 10g Release 2Codename: Paris
XYZ : Soup to Nuts
An “Order” travels through all these pieces Created, validated, transformed, calculated,
aggregated, summarized, etc. Changing something on the JSP in the CSR
application could affect the Product Mgr Dashboard
OWB 10g Release 2Codename: Paris
Metadata : Pre-Paris
Limited to objects that OWB “uses” User Defined Properties (UDP) a start Knows only about “middle section”
Tables, Views, Sequences, Functions, etc
OWB 10g Release 2Codename: Paris
Metadata : Pre-Paris
OWB 10g Release 2Codename: Paris
Metadata : Paris
Can extend the OWB Repository to include your own Classes and Objects
User Defined Objects: Class : SoftwareXReport Objects :
WidgetXReport, WidgetYReport
OWB 10g Release 2Codename: Paris
Metadata : Paris
Note : Possible, not “out of the box”
OWB 10g Release 2Codename: Paris
UDOs : Implementation
First : ClassesCreate IconsetsCreate Classes, Associations, Folders
Second : ObjectsProgrammatically (OMBPlus/Java)OWB Client
OWB 10g Release 2Codename: Paris
UDO Classes : Step 1
Create Iconset
OWB 10g Release 2Codename: Paris
UDO Classes : Step 2
Create CLASS DEFINITION Done in OMBPlus in Single User Mode Requires Knowledge of
First, Second, Third class objects in OWB Repository
Folder DefinitionsAssociation Definitions
“Non-trivial” to say the least
OWB 10g Release 2Codename: Paris
UDO Classes : Step 2 (syntax)
OMBDEFINE MODULE CLASS_DEFINITION ‘MY_MODULE’OMBDEFINE FIRST_CLASS_OBJECT CLASS_DEFINITION ‘EXCEL’ ...OMBREDEFINE CLASS_DEFINITION ‘MY_MODULE’ ADD CHILD_TYPE ‘EXCEL’OMBDEFINE SECOND_CLASS_OBJECT CLASS_DEFINITION ‘WORKSHEET’OMBREDEFINE CLASS_DEFINITION ‘EXCEL’ ADD CHILD_TYPE ‘WORKSHEET’OMBDEFINE ASSOCIATION_DEFINITION ...
NOT exact syntax Oracle should provide “reference” TCL Bayon will publish scripts/information
when Paris is released (maybe an Expert)
OWB 10g Release 2Codename: Paris
UDO Objects : Programmatically
OWB 10g Release 2Codename: Paris
UDO Objects : OMBPlus
Swiss Army Knife of OWBTCL scripting, easy access to OWB Rep
Simple pseudo code:For x in [ file with values ] { create/update JSP objects (values)}
Java for more “advanced” needs
OWB 10g Release 2Codename: Paris
UDO Objects : Programmatically
BUSINESS OBJECTSREPOSITORY
REPORTDEFINITIONSEXTRACT REPORT
DATA FROM BO REP
GENERATE TCLFROM DATAFILES
.TCL SCRIPTS

OWB 10g Release 2Codename: Paris
UDO Objects : Manually
OWB 10g Release 2Codename: Paris
Other Noteworthy Items
Exp/Imp/Snapshots/etc work Public Metadata Views
ALL_IV_GENERIC_ASSOCIATIONS ALL_IV_GENERIC_FCOS ALL_IV_GENERIC_FOLDERS ALL_IV_GENERIC_MODULES ALL_IV_GENERIC_SCOS
Use UD_ so OWB can identify USER DEFINED Classes

Open Discussion
Discoverer : Product to “keep the two in sync?” Can we automate the “Lineage” graphs from
OWB to HTML help site for reporting app? Can we help those “developers” keep their data
in order? Provide impact analysis as a service to other
departments? Can experts be used to simplify UDO
maintenance?
