摘　　要： 本文首先分析了传统分布式计算技术CORBA、DCOM和RMI的特点，揭示了其固有的不足及缺陷：都不太适合于在Internet这样松散耦合、异构的、有防火墙的网络环境下进行电子商务应用系统的设计开发。为满足远程的数据交互、异构平台上不同应用间相互通讯以及穿越防火墙等一系列复杂功能需求，急需寻求一种新型的实际可行的方式构建Internet电子商务应用。 Web服务技术可以解决跨平台、防火墙等复杂问题，能够彻底地实现分布式软件集成，是分布式对象和Internet结合的最佳技术。将Web服务技术引入XML应用系统中可以很好地将Web服务强大的信息交换能力和XML的灵活性结合起来，从而大大提高系统的可管理性、可伸缩性、可维护性和可集成性，为基于Internet的分布式应用提供更强大的功能。 在对XML和Web服务进行充分分析和研究的基础之上，作者研制了一个基于XML／Web服务的新型电子商务应用系统模型——ICX系统。在ICX系统中设计了一种新型的基于XML／Web服务的电子商务应用体系结构，同时研制了一个新型的基于XML／Web服务的数据集成器，以XML为标准数据交换格式，以Web服务为分布式计算机制，通过SOAP消息实现异构应用间的无缝交互。ICX系统数据集成器将来自不同数据源的数据包装为统一的XML数据，并对XML文档进行解析验证，实现相应的集成逻辑，完成客户端的各种操作，对系统屏蔽了异构数据源的差异。ICX系统充分体现了XML的内容与形式相分离的优点及Web服务的新型组件化思想，在电子商务这样涉及大量数据的分布式应用中，大大方便了数据的交换和发布。 本文的最后，运用该新型的ICX系统模型，作者设计、编程、实现了一个基于Internet的分布式电子商务应用示例——冰浪在线航班预定系统，将系 This paper analyzed traditional distributed computing technology CORBA, DCOM and RMI, and find that all of them are not fit for development of electronic business application in Internet which is loose-coupling and heterogeneous network environment with firewall. To realize the remote information exchange, communication between different application on the heterogeneous platform and go through the firewall transparently, it is necessary to look after a new application design method for Internet electronic business application constructing. The technology of Web Service can solve the disturbing problems of inter-platform, firewall, and so on. It can integrate distributed software well, it is the best technology to combine distributed technology and Internet. Using Web Service in XML systems will combine well strong transport capability of Web Service and agility of XML, then make the systems easier to manage, easier to extend, easier to maintain and easier to integration and so provide greater function. On the basic of sufficient analyze and study in XML and Web Service, the author bring forward a new E-business application design model based on XML and Web Service-ICX system. ICX implement a new E-business application architecture and Data Integration Service based on XML and Web Service. With XML as data exchange standard format, Web Service as distributed computing method, ICX system realize the transparent communication between heterogeneous applications through SOAP message. ICX Data Integration Services integrate data of different sources into XML data, shield the difference of heterogeneous data sources, realize the integration logic and respond users through parsing XML documents. ICX reflect well the advantage of XML data that their contents and forms are separated, and new component ideal of Web Service. This advantage has facilitated greatly data exchanging and publishing in distributed applications involving lots of data like E-business applications. In the last part, w
