On Development of Fuzzy Relational Database Applications

Srdjan Skrbic, Aleksandar Takaci.

In this paper we examine possibilities to extend relational data model with mechanisms that can handle imprecise, uncertain and inconsistent attribute values using fuzzy logic. We present a model for fuzzy knowledge representation in relational databases and describe PFSQL – a priority fuzzy logic enriched SQL. We give a brief description of fuzzy JDBC driver and FRDB CASE tool that make complete set of tools needed to develop Java fuzzy relational database application. In addition, a brief survey of research related to application of fuzzy logic in relational databases is given in the introduction. Authors propose several points in which this research and implementation can be continued and extended, contributing to better understanding of fuzzy database concepts and techniques.
