面向服务的体系结构(SOA)逐渐成为信息化建设中的首选架构范式,其主要特征之一即是松耦合.然而,目前还缺少成熟的耦合度度量方法.论文从DoDAF视图出发,从功能耦合、接口耦合和交互耦合三方面,提出了一种针对SOA顶层架构设计的耦合度度量方法,最后以导弹防御系统为例阐述了该度量过程.%Service oriented architecture is emerging as the predominant paradigm of choice for enterprise information systems development,and one of its main characters is loose coupling.However,there are few mature SOA metrics for coupling measurement.In this paper,a set of coupling metrics with functional coupling,interface coupling and interconnection coupling for SOA systems is proposed based on DoDAF.Finally,the missile defense system is presented to exemplify the proposed method.
