Abstract: Induction dependency relation is an important concept in relational databases research. Automatic discovering minimal induction dependency relation plays an important role in data mining. In this paper, we discuss the concept of induction dependency relation, on bases of introducing the rough set-based method of measuring dependency degree, an algorithm of automatic discovering minimal induction dependency relation is proposed.
