The authors investigate the transformation and the preservation of XML referential constraints in XML data transformation for integration purposes in this paper. In the transformation and the preservation, they consider XML inclusion dependencies and XML foreign keys. They show how XML referential constraints should be transformed and preserved using important transformation operators with sufficient conditions. Transformation of schema with its conforming data is an important task in many data intensive activities such as data integration and data warehousing. In recent days, XML is widely used data representation and storage format over the web and hence the task of XML data transformation for integration purposes is getting much importance to the database researchers and developers.
