由于现有的电子商务应用开发方法十分复杂,开发费用也十分高昂,对许多企业来说,要高效地开发可靠的电子商务应用是一个重要的挑战。而Web服务由于具有更简单的面向服务的结构以及更低的开发费用,越来越受到人们的欢迎。本文提出一种服务组合框架,通过这种框架可以采用基于Web服务的方法开发业务集成应用。通过考察Web服务的结构模型和电子商务的结构模式,我们认为本文所提出的框架能够组合用于电子商务应用的规范化Web服务,并且比现有的方法更加高效和可靠。 Due to the complexity of the existing e-commerce application development methods and the high development costs, it is an important challenge for many enterprises to develop reliable e-commerce applications efficiently. Web services are getting more and more popular due to their simpler service-oriented architecture and lower development costs. This paper presents a service composition framework, through which a Web services-based approach to business integration applications can be developed. By examining the structural model of Web services and the structure of e-commerce models, we consider the framework proposed in this paper to be able to combine standardized Web services for e-business applications and be more efficient and reliable than existing methods.
