An elemental processor of fuzzy SQL

Abstract

This paper reports an alternative for implementing an SQL fuzzy extension on a Fuzzy Relational Database System. This proposal tries to build an FSQL processor using representation and manipulation mechanisms offered by the RDBMS which operates as a host. For this purpose, we are based our work on the formulation of a theoretical model of Fuzzy Relational Databases, on the adoption of a scheme for the representation and implementation of fuzzy information on conventional RDBMS, and on the tools for the development of applications available in the host RDBMS. Finally, the FSQL processor is able to translate sentences formulated in FSQL into classical SQL sentences executed directly by the RDBMS adopted as host.
