从不同角度对关系数据库理论中函数依赖(functional dependency,FD)与多值依赖(multi-valued dependency, MVD)及其关系进行了深入研究。从经典关系数据库理论、粗糙集与形式化概念分析出发,探讨了它们对函数依赖与多值依赖的研究视角,得出了关于两种依赖的一些重要结论。

Functional dependency and multi-Valued dependency and their relationships are studied from different angles in this paper.And their research view of classic database theory,rough set theory and formal concept analysis (FCA) to functional dependency and multi-Valued dependency are discussed.Finally,some important conclusions are ob-tained.
