K.E.T.T.L.E (Kettle ETTL Environment) is a meta-
data driven ETL (Extraction, Transformation,
Transportation, and Loading) tool. This means that
no code has to be written to perform complex data
transformations. It is possible to create plugins
to do custom transformations or access proprietary
data sources. Kettle supports most databases on
the market, and has native support for slowly
changing dimensions on most database platforms.
