规则分析作为一种组织符号学研究方法,可以用来在信息系统分析中确定角色的行为模式,而其核心就是对系统状态和规则的描述。本文通过提出RBR(Role,Behavior and Rule)模型和RBR有限状态机对信息系统进行规则分析,以期为既有系统的完善和新系统的设计开发提供依据。文中,RBR模型描述了系统的整体状态和角色权限;RBR有限状态机则把系统状态和权限变化结合起来,描述了系统中无冲突的实时状态和角色权限及其动态变化,既能较容易地验证规则中的权限冲突,确保规则的语义完整,又为信息系统的实时仿真奠定了理论基础。
As a method of organizing semiotics, rule analysis can be used to determine the role model of behavior in the analysis of information systems, and its core is the description of system states and rules. This paper analyzes the rules of the information system by proposing RBR (Role, Behavior and Rule) model and RBR Finite State Machine, in order to provide the basis for the improvement of the existing system and the design and development of the new system. In this paper, the RBR model describes the overall system status and role permissions. The RBR finite state machine combines the system state with the change of authority. It describes the real-time state without conflict and the role rights and their dynamic changes in the system. Verify the authority conflicts in the rules to ensure the rules of the semantic integrity, but also for real-time simulation of information systems laid the theoretical foundation.
