基于Web Service开放系统结构的软件重用

提出了基于时间，空间与应用域三维软件重用行为特征空间的概念，指出软件重用 需解决3个原则性问题，并提出RSRPM面向开放系统的Web Service重用技术体重结构模型。在对RSRPM软件重用模式与实例的分析表明，它不仅重用了Web服务，同时还重用了服务提供系统的数据库结构与数据内容，使得开发周期从4人/月降低到了16人/天，开发效率提高了近10倍。

Web Services-based Software Reuse on Open System Architecture

As a kind of open-system-oriented software reuse technique, Web Services, which not only can solve that three problems in reuse process, but also can solve the interoperation and software reused in distribute and different platform environments, is defined and modeled. Based on the RSRPM (resources, services, roles, protocols and methods) model, the schema and instance of Web Service-based software reuse are studied and the results indicate that this method not only reuses the program of Web Service components, but also reuses the providers database structure and data contents, which decreases the period of development from 4 person-months to 16 person-days and improves the programming efficiency nearly 10 times.
