Data transformation
From AMWA
Data transformation converts data from a source data format into destination data.
Data transformation can be divided into two steps: data mapping maps data elements from the source to the destination and captures any transformation that must occur; and code generation creates the actual transformation program.
The code generation step takes the data element mapping specification and creates an executable program that can be run on a computer system. Code generation can also create transformation in easy-to-maintain computer languages such as Java or XSLT.
When the mapping is indirect via a mediating data model, the process is also called data mediation.(See also Enterprise Service Bus).
