Data mappings can be done in a variety of ways using procedural code, creating [[XSLT]] transforms or by using graphical mapping tools that automatically generate executable transformation programs. These are graphical tools that allow a user to "draw" lines from fields in one set of data to fields in another. Some graphical data mapping tools allow users to "Auto-connect" a source and a destination. This feature is dependent on the source and destination [[data element name]] being the same. Transformation programs are automatically created in SQL, XSLT, [[Java (programming language)|Java programming language]] or [[C++]]. These kinds of graphical tools are found in most [[Extract, transform, load|ETL]] Tools (Extract, Transform, Load Tools) as the primary means of entering data maps to support data movement.
