Audience

This intermediate course is intended for Developers who design OLAP models for use in IBM Cognos BI.


Prerequisites

Delegates should understand the business need for ad hoc queries and analysis, and have experience gathering requirements and analyzing data.

It is also recommended that delegates first attend the IBM Cognos Report Studio: Author Professional Reports Fundamentals (V10.2) - B5258G course.


Duration

4 days.


Objectives

This course provides developers with knowledge of OLAP modeling concepts using Transformer. Delegates will learn how to design, build and maintain PowerCubes for use in IBM Cognos BI so that end users can easily analyze data.
