随着Internet和www的快速发展，基于Web的信息系统变得越来越复杂，它们在关键的任务中也越来越发挥着重大的作用。 XML是为新一代Internet范围内的网络计算而设计的，在分布式计算与应用中起到了不可替代的作用。本文针对企业级用户及其业务的特点，通过对Web应用开发技术的分析，提出了基于XML-RPC的四层B／S系统实现模式，并给出了该模式下相应的硬件架构和逻辑架构。 论文首先分析了在传统Web信息系统开发中存在的一些问题，并结合Web环境下的陕西柴油机厂人劳信息系统开发工作，提出了通过利用UML语言及其扩展来进行Web模式信息系统建模的一般方法和过程。然后，通过对UML为人劳Web信息系统的整体设计建模，分析了系统的软件设计内容，并且采用XML-RPC技术，完成系统的客户层和应用逻辑层的开发工作。 最后，论文结合XML技术、组件技术、DHTML和JAVA技术，为在Web平台上解决XML在数据库应用中的性能问题、动态信息推送技术等难题提出了解决方案，并透过此系统开发实例，探讨所遇到的问题与经验分享。
Web-Based systems are becoming more and more complicated with the rapid evolution of the Internet and WWW and they are developing more and more important function in the primary missions.XML is designed for network computing on the Internet of the next generation, and it will bring about most important effect to the computing and application related to the network. Through the analysis on technology of Web development and deep research on the characteristics of the enterprise users and their system, the architecture of the four-tier B/S application system based on XML-RPC is proposed and the hardware and logical architectures are provided .In this paper, some problems are explained in the traditional web-based system" s development first. Through the development of shannxi diesel engine factory" s RENLAO information system, general method and process which UML is used for the modeling of web-based system are brought forward. Then UML is used for the modeling of RENLAO information system. Meanwhile the design of the software is analyzed and the client layer and application logical layer are developed using XML-RPC technology.Lastly, this paper also provides a solution for the XML performance problem in database application and the dynamic information" s pushing and sending technique of web-based system by bonding XML, DHTML, JAVA and component technology. The encountered problems and development experiences by case study are also discussed.
