Functional dependencies in XML data

Tomasz Piłka, Tadeusz Pankowski

Abstract


In the work we discuss the problem of appearing and checking functional dependencies in XML data. Examining functional dependencies is one of the main factors witch provide data integrity. This problem was successfully examined for relational data. In the case of XML data we must also take the hierarchical structure of data into consideration.

Keywords


XML functional dependency; data redundancy; XML normal form
