Line 1: In [[metadata]], a '''data transformation''' converts data from a source data format into destination data. Data transformation can be divided into two steps: Line 9 ⟶ 8: Data element to data element mapping is frequently complicated by complex [[transformation]]s that requires [[one-to-many]] and many-to-one transformation rules. 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 (programming language)\|Java]] or [[XSLT]]. When the mapping is indirect via a [[mediation\|mediating]] [[data model]], the process is also called '''data mediation'''. Line 77 ⟶ 76: * For further information on data transformation see Chapter 2.4 of [http://geocities.com/timmers_cassidy/thesis.pdf]. [[Category: metadata]]▼ ▲[[Category: metadata]]
