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”

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

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?
