摘要
通过对数据库应用系统开发中用户权限管理实现问题的分析 ,提出了一种基于C/S模式环境下安全性较高、操作方便、实现容易的双重用户权限管理机制 ,即应用程序控制系统模块的操作权限 ,而对于其不能控制的安全性则利用DBMS提供的用户权限管理机制 ,使用户以不同的权限登录数据库 .
The management of user authority in database application system is analyzed, and a duplicate management mechanism of user authority based on client/server is put forward. The using authority of the system modules is controlled by application program itself, and the security which the application program cannot control is guaranteed by user authority supplied by DBMS. The implementation of the user authority management method based on Powerbuild/Oracle is presented. This user authority management method has high security, and its implementation is easy.
