【摘要】 权限管理是系统开发中一个非常重要的环节.在一般应用系统所要求的权限功能基础上提出了一种基于权限冲突的扩展权限管理方法,通过设立权限冲突机制,将具有冲突性质的权限构成冲突集合,并与其他一般权限有效地间隔开来,从而保障了系统的安全机制.在此基础上利用UML语言进行了实现,并成功地应用于应用系统开发中.更多还原

【Abstract】 Authority management is an important link in the management information system development. It works to solve conflict problem effectively. Based on the requirement of application system, a new extended authority management is provided to build sets with conflict functions to separate them from others, therefore, the system security is guaranteed. Furthermore, this new method has been implemented through unified modeling language (UML), and applied in some systems successfully.更多还原
