构件化软件演化信息及演化相似性度量技术研究

Research on evolution information and evolution similarity measurement of component-based software

对软件演化信息的度量能发现软件演化过程中的问题,预测其变化趋势。传统的软件演化信息度量技术主要是以文件、目录或者项目作为度量的基本单位,缺乏在较高抽象层次对软件系统进行度量的能力。在基于构件的软件配置管理模型的基础上,以构件作为软件演化度量的基本单位,提出了一组基于属性变化、适用于构件以及软件系统演化度量的公式(包括较近、较早演化度量,演化相似性度量等),并开发了原型支撑系统。

Software evolution information measurement not only could be used to found software problems during software development and software maintenance,but also to predict software change tendency. However,traditional methods of measuring software evolution information mainly used file,directory or project as the basic unit to track the software change,which lacked the ability of measuring the software evolution in the higher level of abstraction. this paper proposed an approach,which was based on the component-based software configuration management model and took the component as the basic measure unit,to measure the software itself evolution（ such as the latest evolution measurement,the earlier evolution measurement） and the evolution similarity between two software based on the attribute change. Also it designed and implement a prototype support software system.
