0 Transformations in Informatica

Transformations are not only the most fundamental objects in

PowerCenter repository but are also the most important.

Fundamentally, a transformation processes the data. This includes modifying

data, reordering it, transposing it and, in some cases, generating it as well.

There are several built-in transformations such as sorter, rank and aggregator.

But developers can also build custom transformations and embed java code

into PowerCenter. Each transformation is built to perform one unique operation

on data. Developer can combine any permissible combinations of these

transformations to meet their data processing needs
