This Oracle BI 11g R1: Build Repositories training is based on OBI EE release 11.1.1.7. Expert Oracle University instructors will teach you step-by-step procedures for building and verifying the three layers of an Oracle BI repository; you'll begin by using the Oracle BI Administration Tool to construct a simple repository to address a fictitious company's business requirements.

Learn To:

  • Build and execute analyses to test and verify a dimensional business model.
  • Use the Oracle BI Adminstration Tool to administer Oracle BI Server.
  • Use the Oracle BI Administration Tool to build, manage and maintain an Oracle BI repository.
  • Build a dimensional business model to address business intelligence requirements.
  • Validate your work by creating and running analyses, and verifying query results using the query log.

Benefits to You

By taking this course, you'll walk away with the ability to transform your organization’s data into intelligence, which will improve your day-to-day decision making. This new knowledge will help you provide time-critical, relevant and accurate insights. Furthermore, you'll develop skills that will help you become more efficient at building repositories.

Build Logical Business Models

This course will also teach you how to import schemas, design and build logical business models and expose business models to users in the Oracle BI user interface. While constructing the repository, you'll learn how to build physical and logical joins, simple measures and calculation measures.

Model Logical Dimension Hierarchies

You'll then extend the initial repository and learn how to model more complex business requirements. This includes logical dimension hierarchies, multiple logical table sources, aggregate tables, partitions and time series data.

Implement Oracle BI Server Security

Oracle University instructors will also walk you through implementing the Oracle BI Server security and managing the Oracle BI Server cache. You'll learn how to set up a multi-user development environment and use Administration Tool wizards and utilities to manage, maintain and enhance repositories.

Advanced Course Topics

Finally, investing in this course will give you a chance to explore more advanced topics, like implicit fact columns, bridge tables, usage tracking, multilingual environments, write back and patch merge. An appendix is included, which covers architecture and the benefits of the Oracle Exalytics BI Machine.
