以往的互操作机制没有确切地规定业务处理任务的行为,既使业务处理难以准确地进行任务指派,又难以满足Web上异构和分布的应用程序间语义互操作的需求。为此,提出了一套有效的互操作机制,该机制用接口技术抽象化地描述与Web服务调用实例相关的服务行为,有效地解决了服务双方的通讯和协作问题;用适当的调解技术解决交互过程中的各类异构问题。为了证实该机制,给出了在线健康咨询系统应用实例,并深入探讨了该系统的工作机理和互操作实现。 In the past, the interoperability mechanism did not exactly define the behavior of business process tasks. Even if the business process was difficult to accurately assign tasks, it was difficult to meet the needs of heterogeneous and distributed interoperability between applications on the Web. To this end, an effective interoperability mechanism is proposed, which uses interface technology to abstractly describe the service behaviors related to the invocation instances of Web services, and effectively solves the communication and collaboration problems of both service sides. With appropriate mediation techniques, Various types of heterogeneous problems in the interaction. In order to confirm the mechanism, an example of online health consultation system is given, and the working mechanism and interoperability of the system are discussed in depth.
