管理信息系统权限控制的组件化研究与实现

文章提出了适用于管理信息系统()的权限控制策略——用户/MIS—角色/功能权限三级权限控制机制,讨论了权限控制的功能,分析了权限控制的组件划分,实现了基于组件的MIS权限控制系统。考虑到权限控制的通用性和重用性,把权限控制系统封装为大粒度组件直接供其它MIS系统组装、使用,提高了开发效率,降低了维护成本。实际应用表明,基于用户/角色/功能权限策略的组件化权限控制系统方便、灵活、直观地实现了MIS的权限控制。

Research and Implementation of Component-based Privilege Control System for MIS

The privilege control is an essential part in a Management Information System(MIS).First,a three-level pri-vilege control strategy for MIS is present,which is user/role/function privilege.Next,the function of privilege control system based on the strategy is discussed,and component clustering for the system is designed,then,the privilege control system based on component is developed successfully using component technology.Moreover,the system is encapsulated as a large component,and can be directly assembled into other MISs by the way of large-granularity software reuse.The large-granularity component can improve programming efficiently,promote reuse of the core functionality nicely,and reduce cost of maintenance greatly.Running results in enterprises in china show that the component-based privilege control system adopting the strategy for MIS is flexibly and powerfully.
