Research On Mining Classification Rule Based On Rough Set

Rough set theory and its application is a new academic focus, widely used in a lot of fields. Its inherent categorised characteristic makes it especially suited to finding the classification rule. People have researched and developed various kinds of tool software based on rough set abroad, however, the research on rough set in our country is still at theory stage. We fail to keep up a pace in its application, and have no our own tool software based on rough set. These are the background and reason that I write this magisterial thesis.I use rough set theory in mining classification rule in this thesis, and put forward a theoretical model for mining classification rule based on rough set theory. Finally I use PL/SQL to realize the theoretical model on an oracle database with a group of modules, and receive two kind of classification rule. The results are accurate and effective, and have achieved the purpose of the thesis basically. Because each module PL/SQL develops can be made into the storing process or function in the database, for other programming language to transfer, this has offered the foundation of excavating this kind of software for the software developer of using any computer language.
