面向服务的构件规约

Service-oriented Component Specification

目前已有构件规约大多是面向接口方法的型构和行为描述,其主要不足是缺乏针对业务逻辑的完整性描述,而这种规约描述的脆弱性直接影响到构件复用的效率。在需求分析和获取基础上给出构件原子服务、服务的定义及其描述方法;然后在此基础上制定面向服务的构件规约,它是对目前方法级构件规约的扩展;最后从CBD过程层面分析讨论了规约的具体应用。

Most of existing component specifications are focused on describing method-oriented interface signatures and behaviors, but their lack of full description of business logic has influenced the efficiency of component reuse directly. On the basis of requirement analysis and elicitation, atomic services and services were defined and the corresponding methods to describe them were given respectively. And then, service-oriented component specifications （SOCS） were de- fined and the detailed domain application samples were given. SOCS is not a substitute for existed component specifica- tions but an extended version of them. Finally, this paper talked about its application in the level of CBD process.
