Abstract: Thes papter, firstly based on the prototype of fuzzy relational database system (ECNU) shows the representation of fuzzy data in the fuzzy database. Secondly, it defines fuzzy relation and some basic concepts. Then it discusses the fuzzy functionl dependency, normal form and dissociation algebra. Finally it discusses the fuzzy multivalue dependency.
