Re:  What is the relationship between transforming
This punter's US$.02:

Transformation: the generic term for the overall process.

Mapping: the creation of output that corresponds directly to some input on
a fine-grained level.

Filtering: choosing what information to map (or not).

Enriching: adding additional information to that output that does not have
the input as origin, perhaps from a separate data source or some
business/logical rules, possibly constructed by the mapping process itself.
