In this paper, using the concepts of fuzzy sets and possibility theory, a FTS relational model is developed to extend the TS-relational model [Ee Peng Lim et al., 1999]. The extended model integrates local fuzzy databases by merging the respective export fuzzy databases to generate a set of FTS relations of fuzzy multidatabase. A set of algebraic operations is defined to manipulate the FTS relations. A query language FTS-SQL has been proposed to formulate global queries on the FTS relations. An architecture for distributed query processing with a strategy for query decomposition and optimization is also proposed.
