With the advent of XML as a data representation and exchange format over the web, a massive amount of data is being stored in XML. The task of data transformation for integration purposes in XML is getting much importance to the research community. In XML data transformation, a source schema and its conforming data are transformed to a target schema. The source schema often has integrity constraints to enforce semantics. One type of constraints is XML functional dependency (XFD). When a source schema is transformed to a target schema, XFDs can also be transformed. Thus, the problems how schema and data transformation should cause XFD transformation becomes important. We study the effects of transformation on XFDs in this research. Towards this problem, we first define the XFDs over the XML Document Type Definition(DTD) and the satisfactions of XFDs. We then show how XFDs are transformed and valid when the DTDs are transformed. We further investigate whether the transformed XFDs are preserved by the transformed data.
