In this paper, a fuzzy equivalence relation is defined, generally, superseding most of the established results. The technique of employing sets of values for tuple components to express imprecision and redundancy in relational databases was proposed by the researchers in their classic works on fuzzy relational databases. By employing finite scalar domains with similarity relations and special fuzzy number domains, the researchers have demonstrated that the classical properties of uniqueness of tuple interpretations and well-definedness of the relational algebra can be retained in the fuzzy relational database model.
