Research And Application Of Data Warehouse And Mining In Library Management System

With the development of society, the information becomes the third resource besides material and energy in the human society. Meanwhile, the information which is drew from the numbers of the data for the decision seems more and more important, because the aggravation of the market competition and the demand of the informational society. Because the kind of demand not only requires on-line service, but also requires the numbers of data for decision,The traditional database system can't satisfy this kind of the demand. It needs new-type technology to store and deal with data --The data warehouse.Data warehouse is a subject-oriented, integrated, time-variant, non-volatile data set to support management decision-making process. Data storage as a service to enterprise-level applications, mainly to provide users with the advantages of the following four aspects :reducing the burden system to simplify routine maintenance and management;improving data integrity, compatibility and effectiveness; improving the efficiency of data access;providing a simple, uniform mechanism for the inquiry and statements. Online analytical processing (OLAP) data warehouse is one of the most typical applications. It will be different according to the data in the data warehouse aggregate size class, and is expected to count, in front of multidimensional data users view.mining is a lot of data retrieved from the implicit, previously unknown, a potential role for policy makers the knowledge and rules reveal valuable information. it is in in particular widespread In the bank, the telecommunication, the insurance, the transportation, the zero like super city and so on .The data warehouse and the data mining technology also may give full play in the books data management. We may make information resource system rationalization of the library by analysis and the excavation through borrowing, the circulation condition and by the collection booklist storehouse through the reader, thus understand their interest hobby, the research direction, definite individuality...
