Abstract:

This paper discusses the quality of fuzzy multivalued dependency. The inferable theorem is supplemented under the single fuzzy multivalued dependency. The algorithm for computing the dependency radix is provided. The inferable theorem is discussed under the mixed circumstances under fuzzy functional d  ependency and fuzzy multivalued dependency. The conception and theorem of fuzzy embedded multivalued dependency are also introduced.

Key words: （fuzzy multivalued dependency, dependency radix;fuzzy embedded multivalued dependency）
