摘要
Web服务组合已成为跨企业应用集成的主要方法,服务组合需要事务机制来保证其可靠性。由于服务组合自身的特点,传统事务处理方法不适合。首先总结服务组合事务的特点,提出了基于层次的服务组合事务框架,并详细分析了服务组合事务的协调过程。最后给出了服务组合事务协调协议并实现了服务组合事务服务原型系统。
Web Services Composition（WSC） is becoming an important approach to EAI and its reliability needs to be guaranteed by introducing the transaction mechanism. WSC transactions differ from traditional transactions in that they execute over long periods and cross multiple loosely-coupled organizations, so traditional transaction processing mechanism is inappropriate for them. This paper summarizes the characteristics of WSC transaction and presents its multilayer framework, and then analyses the coordination procedure of WSC transaction in the framework, and finally gives its coordination protocol and designs a prototype system for WSC transaction.
