Define the terms: Mapping, Mapplet, and Transformation.

Mapping represents the flow of data between targets and sources. A mapping is a set of target definitions and source linked by objects of transformation which define the data transformation rules.

A Mapplet is a reusable object containing a set of transformations. It enables to reuse that transformation logic in multiple mappings.

A transformation is an object that generates, modifies or passes data. So, it is a repository object. Transformations in a mapping represent the operations the Integration Service performs certain operations on the data in a mapping that are represented. Transformation ports are linked in a mapping or mapplet and the data passes through these ports.
