Oracle BI Enterprise Edition (OBIEE) 11g: Building Repositories

Course:  OBIBR
Duration:  5 Days
Level:  II
Course Summary

This course teaches students how to build and verify the three layers of an Oracle BI repository. Students begin by using the Oracle BI Administration Tool to create a simple repository. Using schemas, they will design and build logical business models, and expose business models to users in the Oracle BI user interface. Students learn how to build physical and logical joins, simple measures, and calculation measures. Validation will be incorporated by creating and running analyses, and verifying query results using the query log.

Modeling more complex business requirements, such as logical dimension hierarchies, multiple logical table sources, aggregate tables, partitions, and time series data is included. 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 is included. Implicit fact columns, bridge tables, usage tracking, multilingual environments, write back, and patch merge will be discussed.
