软件体系结构的概念

The Concept of Software Architecture

软件体系结构作为软件的整体结构，从整个系统的角度来看，除了包括由构件、连接件和约束构成的软件结构之外，软件体系结构还应包括软件完成的业务、执行业务的组织、组织的位置、运行软件所需的信息和技术基础设施等方面的内容。软件体系结构对软件性能和质量的影响是致命的，它与具体的开发过程紧密相关。文章从系统的角度阐述了软件体系结构的概念，基于此概念，说明了以体系结构为中心的开发过程，并结合软件体系结构与软件过程的关系说明了软件体系结构对软件质量的影响，最后总结了研究软件体系结构的目的。

As a whole architecture of software，software architecture includes not only software structure，which is composed of components，connectors and constraints，but also the business completed by software，organizations performing business，locations of organizations，information and technology．Software architecture has great influence on the performance and quality of software，and is related to practical development process tightly．From system viewpoint authors clarify the concept of software architecture，and present the architecture－centric development process in this paper．With discussing the relationship between software architecture and software process，This paper also explores the influence on the performance and quality of software produced by architecture．Finally，this paper summary the purpose that authors research software architecture for．
