Research On Multi-Platform Data Integration Tecnology Base On Campus IC Card System

With the rapidly increasing development of computer technology and the database technology,there are various differences in the fields of hardware,operating system,database and development devices. Therefore,it brings the complexion that the multi-platform and multi-database coexistence in college. Some information systems need the data in the database during the operation,but they can't be accessed directly. Thus a new frame work is needed to be built to solve the problems.This paper firstly analyzes the data integration technologies of some national universities and the application of heterogeneous database systems aboard. Then,a solution was proposed that the data integration based on Campus Card System. Based on XML,the solution designs the data exchange platform structure,studies the relationship between the mapping of data models and data types and the rules of exchange between the database and XML files, defines the tree structure analytical method based on XML Schema,and implements the main function models by experiment of the data integration.To realize the transparent accession of the information sharing database platform,the paper also analyzes the interface model of heterogeneous database and the data mapping based on XML DTD,then gives the campus IC card data integration solve model based on Campus Card System,and finally implements the system model by experiment.The data integration based on data exchange platform and information sharing database platform is a data exchange path to different operation systems of the campus. It makes data exchange more effective and efficient and realizes the core data sharing. It also provides analytical data for decision support system and easily integrates new information system into the whole structure.
