通过需求依赖判定横切关注点

Determination of cross-cutting concerns by requirement dependency

提出了一种定义需求依赖关系以及基于该依赖关系判定需求横切关注点的方法。首先,针对系统资源定义了需求之间原子关系;其次,提出了需求簇的概念以及基于需求之间关系划分需求簇的方法;最后给出了基于需求簇以及需求依赖关系进行横切关注点判定方法和冲突分析方法。通过应用本文方法对一个已有系统提取了相应的横切关注点,验证了本文方法的可行性和有效性。

A method to define requirement dependency and then to determine crosscutting concerns from this requirement dependency is proposed.First,atomic requirement dependency is defined with respect to the system resources.Then,the concept of requirement cluster is provided and the way to group requirements into clusters is introduced.Finally,an approach to determine crosscutting concerns from requirement dependency and conflict analysis is presented.The feasibility and effectiveness of the proposed method are demonstrated by a case study to apply this method to an existing system.
