软件体系结构质量评价概述

1.引言随着软件规模和复杂度的不断增大,对软件质量、成本、进度的要求越来越严格。软件质量是指软件对预期的一系列质量属性组合的满足程度。目前,人们已经普遍认识到软件质量控制在软件特别是大型软件开发过程中对开发效率、成本有重要的影响,甚至关系到开发最终是否成功。高质量的软件在维护和测试阶段的开销较低,复用的潜力大。因此,预测和控制软件质量的成熟技术成为迫切的需要。

Software quality is one of the most important characteristics of soitware system and impacts on tne system's effect, cost and efficiency- As is well known, it's better to improve the quality as early as possible, which can reduce the cost in following development and maintenance. Software architecture is the first activity from problem space to software solution space, therefore, the decisions made during this process are significant to software quality. Software architecture quality evaluation analyzes and predicts quality from architecture level, helping make proper architectural decisions and detecting derivation during following development. This paper summarizes the researches in this area, introducing the purpose, content, state of the art and application status, analyzing the difficulties and discussing the future directions.
