Comparative analysis of xml functional dependencies

The concept of functional dependency plays a fundamental role in relational databases where they are used to specify constraints and to detect redundancies. Similarly, these constraints will play fundamental role in XML as well. Recently XML functional dependencies (XFDs) have been intensively studi...
