摘要
随着B2B应用和电子商务的发展,应用系统要求在因特网环境下能够依据新的需求,快速、灵活地集成各种已有的和新添置的业务应用系统。文章通过扩展现有的WebService描述规范提出了一种支持WebService语义描述的服务资源模型,并在其基础上,通过和基于工作流的服务组合模型的结合,实现了在因特网环境下运行时的动态查找、绑定和调整的服务中介机制。
With the change of requirements and the advance of technologies,especially the popularization of B2B and e-Business,enterprises put forward more demand toward dynamic integrating various applications and services.This paper presents a semantic description model based on the Web Services that supports dynamic services matching and binding to support dynamic application integration over the Internet.Having modified and extended the traditional workflow phi-losophy,it proposes a flexible composition mechanism that coordinates business services according to user requirements in a flexible way.
