OWB is Oracle’s tool to
Collect distributed data in various formats and applications, integrate, and transform it into information suitable for making decisions.
a.k.a. Extract/Transform/Load (ETL)

Why an ETL tool? =

ETL Architecture
Engine
Interpreted (think PERL)
Informatica, Ascential, etc.
Server based
Moves Data to Process
Embedded
Generated code (think C)
OWB/Sunopsis
Runs inside a DB
Moves Process to Data

ETL Engine Architecture

Embedded/OWB Architecture

Review
Need to collect, integrate, and improve data
Data Warehouse built with ETL (read OWB) is the way to accomplish this
OWB is an ETL code generator (embedded) not an engine

Product Packaging
Client and Server Components
Originally distinction between client/server
One installation
Client = GUI
Server = Repositories, RT Service, Name and Address, etc.
Installation = “wicked easy”

Product Installation
Simple steps
Only inputs are:
What directory to install to?
Which Oracle HOME?
Client and Server
ALWAYS INTO A SEPARATE ORACLE HOME

Server Post Installation
Hundreds of MB of Oracle installed into owb10g
Some platform specific code
Ultimate goal to get it into the DB as a pure DB application
edw.company.com ORADB10G OWB10G /oracle/product/oradb10g /oracle/product/owb10g

Client Post Installation

Ongoing Use Client X Client Y Client Z OWB DEVELOPMENT OWB TESTING

Questions for Discussion
During product installation on *nix servers, who should be present?
How many ORACLE HOMES should be present on a server installation?
True/False
Main OWB GUI can connect to multiple OWB servers simultaneously
OWB servers can handle multiple client connections concurrently
