Abstract

This paper provides the theoretical background and important definitions for rough sets. It defines fuzzy rough sets and provides some basic properties of union and intersection of fuzzy rough sets. It then informally presents the basic properties of the rough relational database model. Because the fuzzy rough relational database (FRRD) is an extension of the basic rough relational database model, only a short, informal description of the basic model is provided. The FRRD model is described providing necessary definitions and discussion of operators. Advantages of the enhanced model are discussed
