摘　　要： 随着信息技术在企业信息系统中的广泛使用，传统的封闭式系统暴露出很多难以克服的缺点，系统功能单一、结构死板、难以部署和更新的局限性阻碍了企业信息化的深入发展。为克服这一缺陷，.net平台下智能客户端(smartclient)技术应运而生，其应用显示出了巨大的优越性，成为软件开发中的热点。 本文首先简要地介绍了smart client技术，面向服务(soa)技术的构成及其特点，并详细分析了smart client框架、soa的协议。其次，对模型应用中可能遇到的技术问题进行了研究。引入离线操作模式，在本地缓存数据的最小映射集，客户端操作基于该数据集，恢复连接时再将该数据集和服务器同步，在引入web服务技术对原有业务逻辑封装后，与传统的中间件技术相比，既提高了开发效率，增加了通用性、分布性和应用平台的多样性，并且将取得的数据用xml格式进行封装，在系统间传递，实现了异构系统中的数据集成。 最后，本文为了验证模型的可行性，依照实际需求开发了企业信息管理系统。此系统完全依照模型提出的逻辑结构进行设计，并且对开发中可能出现的技术难点，给出了相应实现方法。它解决了c/s模式下移植困难，维护，升级麻烦，b/s模式下响应速度慢，糟糕的客户体验和网络依赖性强等问题，为用户提供了一个在线和离线都可使用且能智能升级的系统。 With the development of information technology in the enterprise information system, the traditional system exposes a rigid structure, not easy to deploy and update limitations. To overcome this deficiency, Smart Client emerges, its application demonstrates the tremendous superiority, and soon become a hot point. First of all, this paper introduces the technology and characters of Smart Client and SOA, and detailed analyze the Smart Client framework, SOA Protocols. Second, the paper discusses technical problems in research. In offline operating, the client cache minor mapping data in local which it operations base on and synchronizes the data with server while regain the connection. Due to importing Web Services to encapsulate the business logic. Comparing with the traditional middle ware technology, the method increases the develop efficiency, commonality, distributives and Platform diversity. Then encapsulating those obtains data, and format to XML pattern, so as to implement data integration within the heterogeneous system. At last, according to the hospital demand the paper develops a enterprise information management system for verifying the maneuverability of model, and then according to the possible technology difficult within the development of system, the paper give corresponding answers. It resolves the difficulties about the transplantation, maintenance and upgrading of C//S and slow response of B//S and dependence of the worse customer's experience and network Problems, and provide users with an online and offline smart system.
