摘要：As the XML functional dependency and multi-valued dependency impact on the normalization design of semi-structured data, definitions of XML functional dependency, XML multi-valued dependency, path dependency base and the minimal dependency set are given in this paper. Algorithms for minimal dependency set and membership with path expression based on the coexistence of XFD and XMVD are then proposed. Finally, the correctness and termination of these algorithms are proved, and their time complexities are analyzed as well.
