摘要
面对互联网上大量出现的Web服务,如何在动态异构环境中对它们进行组织和管理以便更轻松地构建出各种应用系统是一个亟待解决的问题.本文针对这一问题展开讨论,提出了支持动态服务组合的Web服务三层组织模型,分层次对Web服务进行组织和管理,从而提高了服务发现的效率,实现了灵活的服务组合和替换机制,更高效地支持动态Web服务组合过程.
Facing the appearing of large number of Web services on the net, it is urgent that finding some method of organizing and managing the services in the dynamic heterogeneous environment, in order to make it more easily to develop applications. This paper discusses such problem, and presents a 3-layer Web services organization model for dynamic services composition, which manages Web services hierarchically. This model heightens the efficiency of service discovery, as well as implements flexible mechanism for service composition and replacement , so that it can support dynamic service composition more efficiently.
