In the presence of XML FDs which are specified over DTDs, this paper presents a method based on the hybrid inlining to map XML to relations for storage.

Research of Propagating and Keeping XML Functional Dependency;

When XML document comes forth incomplete information,XML functional dependency has also important meaning for the research of key,normal form and integral restriction for XML document.

XML strong functional dependency definition and XML strong inclusion dependency definition based on consistent path set under the incomplete information circumstances were formalized,judging theorem for XML strong inclusion dependency was studied.

Based on the equivalence of the nodes,the consistency of the nodes,the equivalence of the nodes\' information and the consistency of the nodes\' information,XML strong functional dependency\'s definition was given,inference rules for XML strong functional dependency were presented.

Research on Functional Dependency for XML Based on Tree Tuples;

The Research of the equivalence of XML functional dependency;

Study on Variation Point in Software Reuse Based on Functional Dependency;

This paper extends the concept of function dependency and proves that it has relation to some important concepts in KDD.

Within the category of function dependency, the theory and application of normalization of relation model were studied.

Within the category of function dependency,the theory and application of normalization of relation model are studied.

Analysis of the resolution method of relationship mode base on the function dependence;

A comprehensive description is made in the article of some important concepts concerning theory of normalization of relational data bank, such as function dependence, normal form etc.
