【摘要】 Web Service是分布式计算领域的一项重大技术飞跃,代表着新一代软件架构模式,利用Web Service可以实现在互联网上架构应用软件。Web Service解决了使用传统的CORBA、DCOM这类紧密捆绑的分布式技术时遇到的问题,这些问题主要包括如何通过防火墙、协议过于复杂,异类平台难以集成等。基于这个认识,本文分析了高校当前的网络安全状况及对分布式数据管理的需求,提出了一种基于Web Service架构的分布式信息集成发布系统。该系统实现了跨越防火墙的数据通信,并开发了一系列的Web服务供远程用户调用。用户可以通过Internet获得本系统预置的Web服务单元来装配自己的应用程序,实现应用程序的二次开发,也可以实现多个应用系统的集成。同时本文重点对应用中Web Service的效率和安全性做了讨论,利用SOAP扩展、高速数据缓冲和开发额外的业务逻辑模块等技术来提高Web Service的效率和安全性。该系统能充分利用当前网络状况下的各种资源,使系统具有较好的集成性、延伸性和可扩展性。 本文提出的系统方案能够较好的满足当前高校、企业对分布式数据管理和对应用程序进行二次开发的要求,而且系统架构简捷,投入成本低,是一个比较实用的系统方案。更多还原

【Abstract】 Web Service is considered as an important technical leap in the field ofdistributed computing, which represents a new-generation softwarearchitecture mode for developing application software on Internet. WebService solves the problems we meet when we use the traditional distributedtechnology such as CORBA and DCOM, mainly including the complexity topass through firewall, protocol and the integration of different platforms.According to this viewpoint, this article analyzes the present status of websecurity in college and the requirement for distributed data management, andthen puts forward a sort of distributed information system based on WebService architecture, which solves the problem on how to make data passthrough firewall. The users can apply the reserved logical units to assembletheir own application program, and realize the second development of theirown. The article puts more weight on the efficiency and security in applicationof Web Service, and advocates to enhance the efficiency and security of WebService by making use of SOAP extension, high-speed data cache andexploiting additional business logical module. The system can make good useof resources in the present web conditions, and equip the system with betterintegration expansion and extension.The above system scheme can meet the requirement of college and enterprises to manage distributed data and their second development, meanwhile it has the merit of lower cost and simple construction.更多还原
