Abstract

The work on this paper is an application of intuitionistic fuzzy set theory of Atanassov in relational databases. We introduce the concept of intuitionistic fuzzy functional dependencies in relational databases. The need for introducing such dependencies is justified and explained. Then a detailed analysis of the new notion of intuitionistic fuzzy functional dependencies(iffd) in relational databases is conducted to verify the so-called Armstrong's axioms of intuitionistic fuzzy nature.
