A logic approach to fuzzy relational databases
M.A. Vila, Juan-Carlos Cubero, Juan Miguel Medina, Olga Pons · International Journal of Intelligent Systems · 1994
A new definition of Fuzzy Relational Database is given by using logical concepts. With this definition it is possible to consider several kinds of fuzziness for the database attributes. A Domain Calculus-based query language is also established for the model. It allows us to formulate several types of queries with different lack of precision levels. © 1994 John Wiley & Sons, Inc.
