XML环境下的校园分布式信息系统研究

Research on the Campus Distributed Information Systems under XML

XML为异构系统/数据库间的数据交换提供了有力的支持。研究了使用它结合SOAP、WSDL等Web Services技术解决校园信息化建设中数据重复和信息孤岛等问题的方案。首先进行数据建模,将校园异构系统信息表述为标准的XML格式,通过SOAP封装、WSDL描述实现对信息的请求、响应和传输,解决数据格式不一致的难题,实现异构系统之间的通讯,从而使不同应用系统之间交换数据变得容易,实现校园分布式环境下的资源共享。

XML gives powerful support to data exchange between heterogeneous systems/databases. Study the scheme that solves the problems of data repetition and isolated information island in the campus information construction using XML and SOAP,WSDL and other Web services technology. First,data modeling,describes the campus heterogeneous systems information to standard XML format,realizes the request,response and transmission of information through SOAP packaging and WSDL description,solves the difficult problem of inconsistent data formats,realizes the communi-cations of heterogeneous systems,so that make it easier to exchange data between the different systems,realizes re-sources sharing in campus distributed environment.
