What is a transformation?

SCJP 1.5/1.6 Exam Kit

!!!Answer!!!- From Technical Expert


A transformation is a repository object that generates, modifies, or passes data. You configure logic in a transformation that the Informatica Server uses to transform data. The Designer provides a set of transformations that perform specific functions. For example, an Aggregator transformation performs calculations on groups of data.
Each transformation has rules for configuring and connecting in a mapping. For more information about working with a specific transformation, refer to the chapter in this book that discusses that particular transformation.
You can create transformations to use once in a mapping, or you can create reusable transformations to use in multiple mappings.
