Abstract :
In this paper a new method to judge the grade of normal form for relational database is proposed based on rough sets theory. First, some concepts about INF, 2NF, 3NF and BCNF are given and the principles of rough set theory are discussed. Second, the method to judge the grade of normal forms for a given relation is analyzed using rough sets theory, and some properties of a relation satisfying some grade of normal form are obtained. The study in this paper is a new application of rough sets theory.
