THE FUZZY DATA DEPENDENCIES BASED ON THE SEMANTIC PROXIMITY
Weiyi Liu · Chinese Journal of Computers · 1997
In this paper, the definitions of fuzzy functional dependency (FFD),fuzzy multivalued dependency (FMVD) and fuzzy join dependency (FJD) are given.It is shown that the inference rules of FFDs and FMVDs, which are similar to classical case for Armstrong's Axioms, are sound and complete, and a classical data dependency satisfies the definition of a fuzzy data dependency, also FFD can beviewed as an FMVD and an FMVD can be viewed as an FJD.
