%X For improving the shortcoming of the model of traditional attribute reductions,some researchers proposed the definitions of attribute reduction based on the system entropy and database model.The main merit of attrbute reduction based on databased model is that it can use the efficient database technology to design the algorithm of attribute reduction.So the corresponding algorithm of attribute reduction is efficient.For using the efficient database technology to design the algorithm of attribute reduction b...
