Keywords:Fuzzy relation, Fuzzy relational database, Fuzzy relational algebraic operation, Fuzzy relational database management system
AbstractThis paper introduces a fuzzy relational database model (FRDB) and the management system for it. FRDB is built by extending the classical relational database model with the fuzzy membership degree of tuples in relations. The management system for FRDB with the querying language like SQL is built by using a classical open-source management system.
