This paper concerns integration of selected concepts and methods which are characteristic for rough sets with techniques used in relational databases. The aim is to improve the efficiency of realization of complex computational operations. In this paper we have presented implementations of algorithms of core attributes selection and the method for finding reducts in database system as well as examples of application of such approach.
