Research on Software Requirements Specification Database

提出了一种从文本和可视化软件需求规范自动建立软件需求规范关系数据库的方法。为了提高SRSS的质量，作者开发了一种称为需求框架的需求模型、一种基于文本的需求语言和一种可视化的需求语言。由于需求框架可以转换为关系数据模型，因此每个需求语句都可以看作是一个关系表的元组，作者一直在为SRS数据库开发查询语言和关系数据库管理系统。SRS数据库系统的特点之一是以请求句为例/反例显示答案。此功能有助于从开发人员自己的角度验证SRS。另一个特性是在SR的修改过程中发现需求的变化，这一特性有助于对SR的有效维护。我们已经开发了原型，并通过一些实例验证了我们的方法。

The author proposes a method to build a relational database of software requirements specifications (SRSs) from textual and visual SRSs automatically. The author has been developing a requirements model named Requirements Frame, a text-base requirements language and a visual requirements language based on the model in order to improve the quality of SRSs. Since Requirements Frame can be transformed into relational data model, each of requirement sentences can be regarded as a tuple of relational table.The author has been developing both a query language and a relational database management system for an SRS database. One of the features of the SRS DB system is to show an answer with a requirement sentence as an example/counter-example. This feature contributes to verify the SRS from a developer's own viewpoint. Another feature is to detect changed requirements in modification of the SRS.This feature contributes to effective maintenance of the SRS.We have developed prototypes and validated our method with some examples.
