基于Web Service技术的教育资源集成研究

Education Resources Integration Research Based on Web Service Technology

目的解决高等学校分散、孤立的教育资源遗留系统的现代化问题,实现数字校园软件集成.方法采用Web Service技术提供网络服务,可跨越平台、跨语言、跨操作系统并能穿越防火墙,实现不同部门应用系统集成的目的.结果提出了一种教育资源集成的基础架构方案,分析了教育资源遗留系统的现代化过程中应当注意的问题,给出了一个基于Web Service技术的安全身份认证实例,讨论了设计Web Service时的粒度问题.结论Web Service技术是教育资源遗留系统现代化和数字校园软件集成的一种先进而有效的解决办法,可减少学校信息化过程中的总成本,加速教育信息化的进程.

The paper attempts to propose a feasible solution to the problem of the moderrigation of higher ed- ucation legacy systems, which disperse and isalate the education resoures. In order to realize different departments＇ application system integration the Web service technology is used to provide the network services, which may surmount different platforms, languages and operating systems as well as passing through the finewall. A fundamental integration frammwork of campus education resources is proposed;the problems of the legacy system in its moderrigation process are analysed; an example hased on Wab service technology; the granularity of security status authentication is given, issue about the Web service design is discussed, too. The paper finally draws the conclusion that Web service technology is an advanced and effective way of modernizing the education resource legacy systems, and it will accelerate the process of software integration on the campus.
