The paper deals with fuzzy functional dependencies in relational databases. For data representation a possibility-based approach has been used. It is assumed, that attribute values are represented by means of interval-valued possibility distributions. According to this approach extended definitions of fuzzy functional dependency and fuzzy normal forms have been introduced.
