基于软件需求规范的项目级复用研究

目前的软件复用技术主要围绕软件代码的复用进行研究.而随着开源项目的增多,基于待开发项目的需求文档分析,实现项目级的复用就显得非常有价值.当开发人员获取项目的软件需求后,通常需要对其分析并构建解决方案,然后进行设计与实施.如果能根据项目的软件需求找到相似的历史项目进行复用,可以大大节省项目设计与实施时间.因此,在现有的项...

Research on Project-level Reuse Based on Software Requirement Specification

Most software reuse technologies are focus on coding level reuse. With the increasing number of open source projects, it is quite valuable to realize project-level reuse based on the requirement document analysis of the projects to be developed. When a developer acquires a project’s software requirements, it is often necessary to analyze them, build a solution, and then design and implement it. If a similar historical project can be found for reuse according to the software requirements of the project, the design and implementation time of the project can be greatly saved. Therefore, we present a project-level reuse technology PR-REQ based on requirement analysis. This method firstly analyzes the history of open source projects, and gives the extraction algorithms of the domain information, the functional operation sequence of the code and of data model for the projects. Then, the algorithm of extracting domain information of requirement document, functional operation sequence of use case and data model information are given. Finally, the similarity measure method of requirement document and history project is constructed to find the most similar projects for project-level reuse. In order to verify the validity and accuracy of this method, eight categories of open source projects were downloaded from Github. The experimental results show that this method has good practical value for project-level reuse.
