.NET环境下基于角色的权限管理方案设计

针对开发“煤矿安全隐患识别、预警与整改控制信息平台”的需要，设计了一个在．NET环境下基于角色的权限管理方案。通过分析传统权限控制设计中存在的问题和不足，结合基于角色的访问控制的原理，提出的权限控制系统利用模块编码、页面编码、功能编码和数据库的灵活设计来实现权限的控制。该方案实现了页面级别和页面内功能级别的权限控制，很好的解决了传统权限控制设计的不足，大大的提高了系统的灵活性和可扩展性，并且已经把它作为一个组件实现，可以应用于多种MIS系统的权限管理。

Design of Role-based Access Privilege Management Solution Under .NET Environment

In order to develop a information platform of hidden danger recognition, early warning and control measures for coal mnies, a role-based access privilege management solution under. NET environment was designed. Analyzing disadvantages of traditional access control design, according to the principle of role-based access privilege control,it is put forwad that using module code, page code,function code and skillful design of DB to implement access privilege control. By the solution access privilege control on page-level and function-level access privilege control on pages were realized, resolving disadvantages of traditional access privilege control design and improving system＇s flexibility and expansibility,which was designed as a component,and can be applied in access privilege management of various MIS.
