Abstract

The present paper deals with Codd's relational model of data. In particular, we deal with fuzzy logic extensions of the relational model. Our main purpose is to examine relationships between some of the models which have been proposed in the literature. We concentrate on functional dependencies which is the most studied part of the relational model within fuzzy logic extensions. In addition to the observations on relationships between fuzzy logic extensions of the relational model, our paper brings up several new technical results.
