This preface includes the following topics:


Oracle Warehouse Builder is a comprehensive toolset for practitioners who move and transform data, develop and implement business intelligence systems, perform metadata management, or create and manage Oracle databases and metadata. This guide describes how to use Warehouse Builder Oracle MetaBase (OMB) Scripting Language to:

  • Create a definition of a data warehouse.

  • Configure the definitions for a physical instance of the data warehouse.

  • Validate the set of definitions and their configurations.

  • Generate a set of scripts to create and populate the data warehouse instance.

  • Generate data transformation scripts.

  • Deploy and initially load the data warehouse instance.

  • Maintain the physical instance by conditionally refreshing it with generated scripts.

  • Integrate Warehouse Builder metadata with other Business Intelligence products.

  • Populate Oracle Discoverer EULs and OLAP catalogs for analyzing the data warehouse.

The guide also describes how to create and use Experts. It also lists the run-time and design time public views available in Warehouse Builder. It also describes how users can add new objects called user defined objects to Warehouse Builder.


This guide is intended for data warehouse practitioners who want to access Warehouse Builder functionality programmatically:

  • Business Intelligence application developers

  • Warehouse architects, designers, and developers—especially SQL and PL/SQL developers

  • Developers of large-scale products based on data warehouses

  • Warehouse administrators

  • System administrators

  • Other MIS professionals
