摘要
随着网络技术的发展,应用的体系结构从二层体系结构发展到三层体系结构,而且应用间通过网络交换数据日益频繁。该文提出了利用XML技术实现三层应用体系结构的中间层的网上数据交换模型,详细分析了实现过程中的关键问题。然后给出了使用它改造劳动力信息系统的实例。最后对采用该模型的优缺点作了进一步分析。它实现简单,可扩展性好,并且易于集成各种遗留系统。
With the development of network technology,the architecture of applications is transforming from two-tier to three-tier.Meanwhile,Applications exchange data through Web more frequently than ever.This paper describes a model of exchanging data through Web using XML technology as middleware of three-tier application architecture.It analyzes key problems of the implementation of the model and concludes that the implementation is simple and the system is extensible and is easily integrated with legacy systems.Then the model is applied to change the Labor Management Information System(LMIS).At the end its merits and defects are analyzed.
