> 中文摘要: 软件体系结构设计是软件过程中最为重要的环节之一.在设计阶段完成对软件体系结构非功能属性的评估,对于高质量软件产品的开发非常重要.通过对统一建模语言(UML)的扩展,提出了"建模样式"用于在软件设计阶段对软件体系结构非功能属性进行评估,并结合"可用性链"建模样式在分析软件体系结构"单消息分发-多消息处理"可用性中的应用,给出了建模样式的使用示例.同时,针对建模样式的应用,还提出了"建模知识库"用于管理和维护建模样式,提供各建模样式中标签的参考值.基于UML的建模样式以及建模知识库的使用,可以简化对软件体系结构非功能属性评估的复杂度和工作量,使其可以为软件开发人员所用,并融入到高质量软件开发过程中.
Abstract:The design of software architecture plays an important role in a software process. In the design phase, the non-functional feature evaluation of software architecture would contribute a lot in providing high quality software products. Modeling patterns, which is an extension of UML (unified modeling language), are brought forward for software non-functional feature evaluation in this paper. Furthermore, an example, in which modeling pattern “AvailabilityChain” is used to evaluate the availability of software architecture “1 Message Distributor—n Message Processors”, is given to illustrate the application of modeling patterns. Moreover, to support the application of modeling patterns, “Modeling Pattern Knowledge-Base”, in which modeling patterns and reference values of tags used by each modeling pattern are managed, is involved. UML-based Patterns and Modeling Pattern Knowledge base will simplify the evaluation of software architecture in the software process and contribute a lot in providing high quality software products.
