Study on Paradigm and Its Normalization with Coexistence of XML Functional Dependence and Multivalues Dependence

This paper proposes the paradigm and the corresponding normalization algorithms with coexistence of eXtensible Markup Language (XML) functional dependence and XML values dependence. The concepts of redundancy and keys are firstly described in this paper, while the paradigm with coexistence of XML functional dependence and XML values dependence is defined later. Then, the non-redundancy judgment theorem is also also presented. Furthermore, the XML document tree normalization algorithm is introduced, while the capability to be terminated, validity, and computation complexity are analyzed and proved. Finally, the effectiveness of the algorithm is demonstrated by the experiments.
