Transformations

Transformations

A transformation is an object that generates, modifies, or passes data.
Informatica Developer provides a set of transformations that perform specific functions. For example, an Aggregator transformation performs calculations on groups of data. Transformations in a mapping represent the operations that the Data Integration Service performs on the data. Data passes through transformation ports that you link in a mapping or mapplet.
Transformations can be active or passive. Transformations can be connected to the data flow, or they can be unconnected. For more information about transformations, see the
Developer Transformation Guide.
