The complexity of real applications in the fields of intelligent information systems has required fuzzy data models for an expression and a processing of uncertain and imprecise data. In this paper we propose a Fuzzy Association algebra (FA-algebra) as a query algebra for a new Fuzzy Object Oriented data model(F-model). The F-model is investigated as some fuzzy extensions of an Object Oriented data model, in which fuzzy objects and their fuzzy associations are represented. In the FA-algebra, fuzzy objects and fuzzy associations are uniformly represented by fuzzy association patterns. As the results of operations by the operators defined in the FA-algebra, the returned fuzzy association patterns contain the truth values which mean the degrees of suitability of patterns as answers for the queries. The completeness of the FA-algebra is shown.
