This document provides an overview of the topics that will be covered in an Informatica Power Center 7.x/8.x/9.x training course. The training will cover fundamental concepts like ETL logic, data warehousing, data modeling, and the differences between OLTP and OLAP systems. It will also provide in-depth training on using Informatica Power Center's core components like the Designer, Workflow Manager, Transformations, Mappings, Source Analyzer and Target Designer to develop ETL mappings and workflows. Advanced topics like complex dimension mappings, rapidly changing dimensions, parallel pipelines and debugging/optimizing performance will also be covered.
