GEFRED - A GENERALIZED-MODEL OF FUZZY RELATIONAL DATABASES

In this paper, we present a Fuzzy Relational Databases model whose mai n characteristics are: the integration of previous models in the same framework, representation capabilities for a wide series of fuzzy info rmation, and a coherent and flexible handling of it. This model aims t o solve each problem of representation and handling of fuzzy informati on taking into account its specific nature, and hence it allows the us er to. choose the comparison operator and the fuzzy compatibility meas ure to be used in a query. Besides, it permits the user to specify the precision with which the conditions involved in a query are satisfied .
