脱耦权限组件模型研究

Decoupled privilege component modeling

权限管理是现代信息系统设计的核心内容之一,降低权限管理实现与宿主系统的耦合、提高权限系统的复用能力,对信息系统降低研发成本、增强系统健壮性有着重要意义.本文从信息系统解耦相关概念出发,分析脱耦组件的需求模式,提出了一套基于消息服务及RBAC技术的脱耦权限组件设计结构并予以实现.该组件具有独立的权限管理设计模式,并借助消息服务达到了易部署的目的,一定程度上拓宽了权限管理的设计模式.

Privileges management is one of the core contents of modern information system design,It＇s important to decrease the cost of research and development and strengthen information system robustness by reducing the coupling between privileges management and host system and improving the reuse ability of privileges system.In this paper,we defined the related concept of decoupling at the first,and base of analyzing the decoupling component requirements,we presented a design structure based on MOM（message oriented middleware）and RBAC and implemented it.This component implement had independent host application,and with the help of MOM to achieve the purpose of easy deployment at a certain extent widening the design mode of privileges management.
