Yan Li Dai

With the development and improvement of information technologies and database, data storage is used by more and more enterprises, institutes and departments, which requiring more intelligence and more accurate ways of data mining. Multidimensional data mining technology, including On Line Analytical Processing technology and data mining technology, is created on the basis of increasingly improved data warehouse technology and OLAP technology, making it more convenient for users to choose and analyze. This paper mainly researched and analyzed the multidimensional data mining of rough set, including concepts of multidimensional data and rough set, decision tree technology integrated with rough set, and the design of multidimensional data mining based on rough set
