Fuzzy set theory has been extensively applied to extend various database models and resulted in numerous contributions, mainly with respect to the popular relational model or to some related form of it. To satisfy the need of modeling complex objects with imprecision and uncertainty, recently many researches have been concentrated on fuzzy object-oriented database models. This paper reviews fuzzy database models, in which fuzzy relational and object-oriented databases are discussed.

Keywords: database models, fuzzy set, possibility distribution, fuzzy conceptual data models, fuzzy logical database models
