摘要
详细介绍了基于BPEL语言的可视化Web服务组合流程建模工具的体系结构;引入节点和弧的概念实现可视化流程编辑器;采用图形化方法和流程图到WS-BPEL元素的映射技术,实现了Web服务组合流程模型的建立、编辑和配置等功能,简化了抽象流程到可执行流程的转化;提出了基于Web服务QOS约束的服务查询、QOS本体表示和QOS筛选方案,使得符合用户需求的Web服务能够被动态灵活地绑定到业务流程中。
A framework of visual web services composition business model tools is described. Visual business editing tools is implemented by using arcs and nodes. A tool is created by a graphical method and a technology which implements a mapping from flow diagram to WS-BPEL elements, the transformation is simplified from an abstract process to an execution process. A solution is provided to the query and the selection of web services based on the QOS of web services, the solution can dynamically compose these web services which meet the needs of customers into a business process.
