摘要
面向视点(Viewpoint-Oriented)的方法能够根据系统参与者的不同视点完整地描述系统的需求。但是传统的面向视点的方法在需求分析的过程中没有考虑到视点和关注以及关注之间横切关系的作用,从而导致系统难以雏护和演化。本文提出一种基于PREView方法的方面需求识别扩展,在保持原有方法优点的同时,增加了原方法对于方面需求的支持,使得在需求分析阶段就开始消除横切的影响。
The requirements of some systems can be described completely by viewpoint-oriented approach according to the differ- ent viewpoints from different system participators.But the relationships between viewpoints and concerns and between concerns and concerns are ignored in the analysis process of traditional viewpoint-oriented requirements,which made it difficult for the system to be maintained and evolve.In this paper,we propose a recognition extension of aspectual requirement based on PRE- View---a kind of viewpoint-oriented approach.Our extension supported identification of aspectual requirement and kept the mer- its of PREView.Therefore,the affect of crgsscutting can be eliminated at the beginning of software life cycle.
