PowerCenter: Developer, Level 2

Course Overview

This course is applicable to software version 10. Explore Informatica PowerCenter 10.0.0 which is comprised of a server and client workbench tools that Developers use to create, execute, monitor and schedule ETL processes. Work through the PowerCenter Designer, Workflow Manager, and Workflow Monitor tools while performing tasks such as creating source and target definitions, transformations, mappings, reusable objects, sessions and workflows to extract, transform and load data.
