视点一致性是多视点需求工程中的核心,如何合理有效地定义视点的一致性,直接影响到视点一致性的检查和不一致的管理.介绍视点一致性定义的相关研究,从形式上将视点一致性的定义分为3种类型. 基于问题框架的方法标识和表示视点的方式,可导致视点不一致的相关因素进行了分析,且从内容和形式两方面讨论视点一致性的定义,及其相关性质.
Consistency of viewpoints is the kernel problem of muhiview-oriented Requirements Engineering. In the consistency checking and inconsistency management of viewpoints, the definition of consistency between viewpoints is very important. The related researches of the definition of consistency between viewpoints are summarized firstly, at the same time, three types of definition of consistency between viewpoints are presented. Then based on the identity and expression style of viewpoint derived from Problem Frame method, the factors of inconsistency among viewpoints are analyzed in details and the definition of consistency between viewpoints and the corresponding characteristics are discussed.
