The concept of fuzzy multivalued dependencies (FMVDs) is introduced. It is concluded that FMVDs are more generalised than classical multivalued dependencies. A set of sound and complete inference rules, similar to Armstrong's axioms are proposed to derive more dependencies from a given set of FMVDs.

Based on the semantic equivalence degree the formal definitions of fuzzy functional dependencies (FFDs) and fuzzy multivalued dependencies (FMVDs) are first introduced to the fuzzy relational databases, where fuzziness of data appears in attribute values in the form of possibility attributions, as w

In this paper, we want to set up a series of design methods for relational databases based on the fuzzy inheritance relationship. We look upon the relationship between a class and its subclass as a scheme constraint. We present the concept of fuzzy inheritance dependencies and show that the inferenc
