系统建模的角色优先原理研究

A study on the actor-first theory in system modeling

提出了在利用UML语言进行系统建模时角色优先的概念,对该概念进行了原理性的讨论。认为角色优先原理指在系统建模时,首先考虑的对象是用户角色,从而使得应用系统的研究出发点从考虑系统功能转换为考虑用户角色需求。

The actorfirst theory in system modeling with UML language is put forword and discussed in theory.The theory means that the user roles should be considered firstly in system modeling,it shifts the start of an application system from considering the functions of the system to considering the demands of user roles.
