| With the improvement of user'desire disagree for knowledge, More and more people no ever discontent with the knowledge which get before, in order to suit this situation, the most important problem study of this paper focus on improving the efficiency of KDD , especially with the high speed development of database technology, Many Data Warehouse stored with all kinds of complex data type have proposed more grim challenge for KDD. This paper proposed the static of KDD which based on Date Warehouse. That is flexible algorithm static and process drive static, and proposed one new model of KDD used the two static above.The main difficulty in this paper is solution of KDD static problem such problem was depicted as under the environment of Data Warehouse, how to optimize the KDD static, Improve the efficiency of Date Mine, information and data could be converse to knowledge which could be used for user and supported for decision-making more quickly; and the static of choosing different Data Mine algorithm for different date. And hope that this static could be an effective bridge between Data Mine algorithm and KDD based on Data Warehouse, with this static ,during the process of KDD based on Data Warehouse, not only beginner but also expert could use the Data Mine algorithm effectively.During the study process of this paper, the writer through read and study a large number of books, materials and related theory about Data Warehouse and KDD, made this paper had more deeply basic theory, and through the study of result about KDD and KDD based on Date Warehouse which had exited, made a induction and summary of some Data Mine static'advantages and disadvantages, and analyzed the feasibility of the static in this paper. Provides certain references for theory research of based on Data Warehouse KDD, simultaneously, could have certain guiding sense to the enterprise and individual user's actual operation. |
