Fuzzy relation database, fuzzy functional dependency, fuzzy logicAbstract
In this paper we establish a connection between one fragment fuzzy logic and the theory of fuzzy functional dependencies on the basic of the semantic distance. We give a way to interpret fuzzy functional dependencies as formulas in fuzzy logic. For a set of fuzzy dependencies $F$ and single fuzzy functional dependency $f,$ we show that $F$ implies $f$ as fuzzy functional dependencies if and only if $F$ implies $f$ under the logic interpretation.
