So it is necessary and valuable to research requirements modeling language and technique from the perspective of behavior. This paper presents a lightweight behavior based requirements modeling language BDL with formal syntax and semantics, and a general-purpose requirements description model BRM synthesizing the concepts of viewpoint and scenario. BRM is good for modeling large and complex system due to its structure is very clear. In addition, the modeling process is demonstrated through the case study On-Line Campus Management System. By lightweight formal style, BDL & BRM can effectively bridge the gap between practicability and rigorousness of formal requirements modeling language and technique.展开更多
