Study Of Application Of Data Mining In The Database Of Campus Card

At the present time, many universities have used the e-card system to manage all the consume in the campus. With the use of e-card, we can consolidate the management to all kinds of messages, and simplify the steps of management.Based on studying the campus card transaction data , through the comprehensive use of data warehousing, OLAP, data mining technology ,we tap the campus card useful knowledge . First introduced by the data warehouse, OLAP technology and data mining technology and mining of the basic tenets of the core algorithms, and JiangXi Normal University campus card against the card information conducted a preliminary analysis, the use of the data warehouse concept, which involves Multiple databases for the integration and conversion to form a comprehensive database to mining and to the establishment of a data warehouse .Combining theory on the forefront of some of the author in the field of exploration and efforts to try: The clustering method of K-means algorithm-based cluster analysis, the initial realization of the campus card data from the excavated for the construction of schools, and other aspects of the decision-making Meaningful decision-making knowledge.Oracle database system is business as a source of data, using data warehousing, OLAP, data mining, show the prospects and improve the decision-making knowledge easy to understand the degree of expression.Through the realization of the system, the excavation of the campus card transaction information of the general steps and methods used B/S Data Show structure to facilitate the decision-making departments of customer data analysis, and ultimately achieving scientific decision-making, enhance business economic efficiency, improve School management objectives.This paper will be the knowledge that the work of excavation for the campus card data analysis, and knowledge of these schools to support decision-making support for the work of innovation is meaningless.At the same time, work now for the next school comprehensive information access to knowledge of further study, the structural integrity of the analysis platform and to achieve a higher level of leadership support for the overall decision-making framework to lay a solid foundation.
