Course Overview

This course can be delivered through a five-day instructor led format or through our on Demand Labs Plus offering, which is comprised of 15 modules and 3 to 35hours class both theory and Lab! The course introduces students to "nformaticaPower#enter $!% through lecture and hands-on e%ercises! The course is designedfor Database Developers who are new to "nformatica Power#enter!

"nformatica Power#enter is a collection of thic& client wor&bench tools thatDevelopers can use to create, e%ecute, monitor and schedule 'TL processes!

The course will introduce attendees to wor&ing with the Power#enter Designer,(or&flow )anager, and (or&flow )onitor tools, performing tas&s such as creatingtransformations, mappings, reusable ob*ects, sessions and wor&flows to e%tract,transform and load data! They will develop cleansing, formatting, sorting andaggregating procedures! They can learn how to use routers, update strategies,parameters +variables and overrides! This course will cover many different types of loo&ups, such as cached, persistent, dynamic and multiple row returns! (or&flowtas&s will be created to define a set of instructions for e%ecuting the 'TL!

Course Objectives

fter successfully completing this course, students should be able to

. /se "nformatica 0upport to resolve uestions and problems with Power#enter $!%

. /se Power#enter $!% Designer to build mappings that e%tract data from a sourceto a target, transforming it as necessary

. /se Power#enter transformations to cleanse, format, *oin, aggregate and routedata to the appropriate targets!

. Perform error handling+trapping using Power#enter mappings

. /se Power#enter $!% (or&flow )anager to build and run a wor&flow whiche%ecutes a sessions associated with a mapping

. Design and build simple mappings and wor&flows based on essential businessneeds



. Perform basic troubleshooting using Power#enter logs and debugger
