基于Web服务的SOA原型系统架构

Service orientated architecture stereotype with Web service

基于SOA生命周期的建模、组装、部署和管理四个阶段,提出了一个基于Web服务标准的SOA原型系统架构。在组装阶段的服务选择引入基于本体的服务匹配器,并引入了服务质量(QoS)管理器;在管理阶段保证组合服务的正确执行提供了监控器、异常处理器和事务适配器和基于多值背景值依赖的方法的组合服务QoS管理器。提出了在组装阶段和管理阶段的双层QoS管理,为Web服务组合和SOA架构的研究提供了参考。

A SOA stereotype with Web service specification is proposed according to the life cycle（i.e.,modeling,assembly,deployment and management） of SOA in this paper.In the assembly phase,the services matcher with ontology is adopted to solve service heterogeneous problem.And QoS management of Web service is also adopted.In the management phase,the process monitor,exception handler,transaction adapter and QoS management with many-valued context of composite service are provided to ensure composite services executed correctly.Therefore double QoS management in the assembly phase and management phase is realized in the stereotype which provides reference to the research of Web service composition and SOA.
