Credit Card Data Mining Research Based On The Data Warehouse Theoy

The thesis is mainly concerned with the data mining technology of credit card based on Data Warehouse after explaining relative theoretical knowledge started with an actual question. In this paper, the subject background) the application of data mining in credit card and present research and development trend are firstly produced. Secondly, the primary concepts data construction and design method and step of DW are narrated. Then the technology of Data Mining(DM) in DW tools layer is illustrated in detail. We take the data of credit card as example to illustrate application theory and realization method of data warehouse. Next the solution of the data mining system of credit card is put forward; The technology of data mining of credit card based on DW is analyzed. Finally, some developing directions of DW in the future are predicted.The purposes of the thesis are more scientific on the aspects of auditing credit rating and controlling risk and to provide scientific foundation for managerial decision.
