摘要： 面向服务的软件开发关注两个方面:服务设计和服务集成。针对协作构件接口方法之间的相关性对服务的形成所具有的约束,提出了服务构件的模型,对构件方法相关性进行了分析并探讨了服务形成的规律,使得服务操作成为自包含的、相对独立的行为粒度;提出了“调用点环境化”的概念和方法以降低服务之间调用依赖和便于服务集成。

Abstract: The service-oriented development includes two aspects: service design and service integration. Based on the restraint from the correlation among the methods of cooperative components to form Web services, the paper proposes the model of service component, analyses the correlation and discusses the rule to form service. Furthermore, it puts forward the concept and method of "invoking in infrastructure" to reduce the dependency relationship during invoking Web services.
