【摘要】 文章通过一个协作式客户机/服务器软件系统的实例阐明了设计不同系统体系可复用扩展软件构架的一种方法。笔者提出的构架,将使用构架描述语言进行定义,通过软件复用的三个层次(独立于应用域的,领域特有的和应用特有的),有机地组织起来。构架由可复用领域的特定黑盒构架模式和可扩展领域的特定白盒构架模式组成。文章重点阐述了软件构架中复用的不同层次以及构架如何实现扩展。更多还原

【Abstract】 This paper describes research into the design of reusable and extensible software architectures for families of systems.The approach is illustrated by an example of a federation of client/server software systems.The architecture,which is specified in an Architecture Description Language,is organized at three levels of software reuse,application domain independent,domain specific,and application specific.The architecture is composed of reusable domain specific black box architecture patterns and extensible domain specific white box architecture patterns.The paper describes the different levels of reuse in the software architecture and how the architecture may be extended.更多还原
