Oracle BI Suite EE 10g R3: Build Repositories

This course is held in Oracles facilities in Kista

This course provides step-by-step procedures for building and verifying the three layers of an Oracle BI repository. Students begin by using the Oracle BI Server Administration Tool to construct a simple repository to address a fictitious company's business requirements. Students 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, students 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.

Students then extend the initial repository and learn how to model more complex business requirements, such as dimension hierarchies, multiple logical table sources, aggregate tables, partitions, and time series data. Students also learn how to implement OracleBI Server security, manage OracleBI Server cache, set up a multi-user development environment, and use Administration Tool wizards and utilities to manage, maintain, and enhance repositories. Finally, students are exposed to more advanced topics, such as implicit fact columns, bridge and helper tables, usage tracking, optimizing query performance, and multilingual environments.
