Oracle Data Warehouse

1. Oracle: Data Warehouse Builder

2. What Is Oracle Warehouse Builder?
– Oracle Warehouse Builder is Oracle’s industry-
leading enterprise business intelligence integration
design tool.
– Warehouse Builder manages the full life cycle of
data and metadata for Oracle Database.
• Provides an easy to use, graphical environment to design,
deploy, and manage business intelligence systems
• Enables the extraction, transformation, and loading (ETL)
of data for quality information in the Oracle database
• Protects and leverages customer investment in the Oracle
technology stack through data and metadata integration

8. Steps for Setting Up the
Warehouse Builder Environment
1. Verify the installation
requirements.
2. Determine the environment
configuration scenarios.
3. Prepare the server
infrastructure (OS, Database).
4. Install optional components.
5. Install Warehouse Builder.
6. Create the Warehouse Builder
repository.

9. Installing Warehouse Builder
– Warehouse Builder uses
Oracle Universal Installer
to install components
and to configure
environment variables.
– OUI installs all the
software at the same
time.
– This software can play
the role of client or
server software
depending on where you
run the installation.

10. Creating a Warehouse Builder
Repository
– Two ways of defining a Warehouse Builder repository:
• Using Repository Assistant (wizard)
• Using the OMB Plus OMBINSTALL OWB_REPOSITORY
command
– Two ways to create a repository when using the
Repository Assistant:
• Basic Install
• Advanced Setup

11. Logging In to OWB Design Center
If you have not yet created a
repository, click the Get Started
button to create one. This launches
the Repository Assistant.

12. Design Center
Menus

Project Explorer
Connection Explorer
Project Explorer: Holds all project organized
metadata (also known as your design).
Connection Explorer: Holds all information
about physical locations and how these are
managed in control centers
Global Explorer: Holds all objects that are
shared among users across the repository. It
holds pre-built content, and you can create your
own content for sharing across projects.

13. Projects
– A project is the highest-level object in Warehouse
Builder.
– You should have all the objects you need in one project,
as objects are not shareable across projects.
Project A
Data Mart
Mapping Warehouse

Project B

module-Sales

18. Deleting a Project
You cannot delete the current
active or expanded project, or
the only project in a repository.
