OWB 10g Release 2 Codename: Paris What is OWB? Extract / Transform / Load (ETL) OWB is a CODE GENERATOR  PL/SQL, XPDL, CTL files

OWB 10g Release 2 Codename: Paris Why an ETL tool? =

OWB 10g Release 2 Codename: Paris OWB : Metadata Metadata is central to OWB architecture A working solution requires 1. Build things “logically” 2. Build PL/SQL from design model 3. Execute actual code (runtime) Metadata is the oft forgotten “orphan” of data warehousing

OWB 10g Release 2 Codename: Paris Metadata : Impact Analysis What’s the possible DW impact of a change to the CATEGORY DATAFILE in my SALES application?

OWB 10g Release 2 Codename: Paris Situation : Company XYZ You have a Data Mart that produces “Sales” reports BUT WHAT DOES IT MEAN!?!?

OWB 10g Release 2 Codename: Paris Metadata : Lineage Does the SALES cube include data from the OE Schema?

OWB 10g Release 2 Codename: Paris Metadata : Logic AND Code BUSINESS LOGIC CAPTURED

OWB 10g Release 2 Codename: 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, Feedback

OWB 10g Release 2 Codename: Paris Company XYZ : “start to finish” One “order” travels through all these pieces  Touched, validated, transformed, calculated, aggregated, summarized, etc.  Changing something on the JSP in the CSR application could affect the Product Mgr Dashboard

OWB 10g Release 2 Codename: Paris OWB Metadata : Pre-Paris Limited to objects that OWB “uses” User Defined Properties (UDP) a start  Could “tag” a table as relating to an Java class Knows only about “middle section”

OWB 10g Release 2 Codename: Paris OWB : User Defined Objects Can extend the OWB Repository to include your own Classes and Objects Blank Check:  Class : SoftwareXReport  Objects : WidgetXReport, WidgetYReport

OWB 10g Release 2 Codename: Paris “Management” pre-Paris

OWB 10g Release 2 Codename: Paris “Management” Paris Note : Possible, not “out of the box”

OWB 10g Release 2 Codename: Paris UDOs : Implementation First : Classes  Create Iconsets  Create Classes, Associations, Folders Second : Objects  Programmatically (OMBPlus/Java)  OWB Client

OWB 10g Release 2 Codename: Paris UDO Classes : Step 1 Create Iconset

OWB 10g Release 2 Codename: 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 Definitions  Association Definitions “Non-trivial” to say the least

OWB 10g Release 2 Codename: 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 2 Codename: Paris UDO Objects : OMBPlus Swiss Army Knife of OWB  TCL scripting, easy access to OWB Rep Simple pseudo code:  For x in [ file with values ] {  create/update JSP objects (values)  } Java for more “advanced” CMI Doesn’t appear to be useful here…

OWB 10g Release 2 Codename: Paris UDO Objects : Programmatically BUSINESS OBJECTS REPOSITORY REPORT DEFINITIONS EXTRACT REPORT DATA FROM BO REP GENERATE TCL FROM DATAFILES.TCL SCRIPTS OWB REPOSITORY

OWB 10g Release 2 Codename: Paris UDO Objects : Programmatically

OWB 10g Release 2 Codename: Paris UDO Objects : Manually

OWB 10g Release 2 Codename: 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 knows it’s USER DEFINED classes

OWB 10g Release 2 Codename: Paris Open Discussion Discoverer : Product to “keep the two in sync?” Automate the “Lineage” graphs from OWB to HTML help site for reporting app? Help those “developers” keep their data in order (provide impact analysis as a service to other departments)? Experts can be used to simplify the UDO maintenance?
