| Abstract: | The cause-effect relationship among the attributes in the relational database is analyzed using rough set theory. A method of mining rules from relational database is studied. The reduction of conditional attributes and the strategy for smallest reduction of finding rules are discussed in detail and the algorithm is put forward. The method presents a new approach of acquiring knowledge from databases. |
