可重用信息系统框架设计

软件重用是软件界追求的目标，人们正努力实现基于框架、体系结构和需求的重用，但具体实现技术还不够成熟。框架是可重用的特定领域应用软件的半成品，在框架上定制可以建立具体的应用系统。一个好的框架可大大节省开发时间，降低开发成本。简要介绍了软件重用和框架，提出了一个用于信息系统领域的框架设计，并给出了该框架的体系结构和开发模型。

Design of reusable information system framework

Software reuse is the goal of software industry at present and people are striving to realize framework reuse, architecture reuse and requirement reuse, but the technology is not mature. A framework is a reusable, and semi-complete application in the specific domain that can be customized to build a complete application by an application developer. A good framework can reduce the time and cost spent on application. Software reuse and framework are introduced first, then a reusable framework which is used in information system domain is presented and architecture and model are described.
