【摘要】 如何充分利用原有系统的资源,建立开放灵活、低代价的系统已成为高校信息化建设的关键。面向服务的体系结构(SOA)为解决分布式环境中软件重用、扩展和提高软件开发效率提供了解决方案。分析了高校信息化建设中面临的“信息孤岛”问题,研究了利用Web服务实现基于SOA的分布式系统的有效方法,并给出了采用SOA体系结构开发的科研信息系统的框架、集成原理和Web服务实现等关键实现技术。更多还原

【Abstract】 How to make most of existing information systems and set up low-cost,open and flexible integration system have already become the key factor to constructing information system in universities.Service oriented architecture(SOA) provides a solution to im-prove the reusability,scalability and efficiency in software development.The "information island" problem in the process of constructing information system in universities is analyzed,then an effective method to implement SOA based on distributed scientific research in-formation system with web services is thoroughly investigated.Key issues,such as system architecture、integration principle and web services implementation are introduced.更多还原
