摘　　要：软件框架为特定领域内的软件重用带来了极大的便利,然而随着业务系统的发展,传统的基于组件的软件框架已经越来越难以满足业务系统发展的需要.面向服务架构作为新型的软件架构,具有极大的灵活性和扩展能力来支持业务系统的发展需要,在没有具体的指导规范下,SOA开发是相当困难的。服务组件架构作为目前SOA最佳的编程模型,对其深入研究和理解,将有助于快速开发基于SOA的应用。从SCA的基本概念出发,分析了SCA的组成结构,在此基础上给出了SCA框架元模型,分析研究了实现扩展类型,并给出了具体应用示例。Software framework brings lots of conveniences for software reuse in specific domains.But with the development of business systems,traditional component-based software framework has become increasingly incompetent to meet the developmental requirements of business systems development.Service-oriented architecture（SOA） is a new bright software architecture with great flexibility and scalability to support the developmental requirements of business systems.But in the absence of specific guidances or specification,developing SOA application is very difficult task.Service Component Architecture（SCA） is the best one of all SOA development approachs.So study and research of SCA approach will be very useful for rapidly developing SOA-based applications.In this paper,the basic concepts of SCA will be introducted,and the SCA basic structure will be analyzed.Following these results,the SCA framework meta-model and a study result of implementation extension will be given.Then a specific example is given.
