Oracle BI Server Administrator 10g: Build Repositories Rel 1

What you will learn

This course provides step-by-step procedures for building and verifying the three layers of an Oracle BI repository: the Physical layer, the Business Model and Mapping layer, and the Presentation layer. Begin by using the Oracle BI Server Administration Tool to construct a simple repository to address a fictitious company's business requirements. Learn to import schemas, design and build logical business models, and expose business models to users in Oracle BI Answers. In the process of constructing the repository, learn how to build physical and logical joins, simple measures, and calculation measures. Students also learn how to validate their work by building queries and verifying query results using Oracle BI Answers and the query log.

Extend the initial repository and build expertise in modeling more complex business requirements, such as dimension hierarchies, multiple logical sources, aggregate tables, partitions, and time series data. Gain skills in implementing Oracle BI Server security, managing Oracle BI Server cache, setting up a multi-user development environment, and using Administration Tool wizards and utilities to manage, maintain, and enhance repositories.

Learn To:
  • Use the Oracle BI Administration Tool to build, manage, and maintain an Oracle BI repository
  • Use the Oracle BI Adminstration Tool to administer Oracle BI Server
  • Build a dimensional business model to address business intelligence requirements
  • Use Oracle BI Answers to build and execute queries to test and verify a dimensional business model
