摘　　要：基于C/S模式的考试系统,成绩一般都存储在各个考点的数据库中,这样数据库的成绩存在着许多的安全问题,如成绩易被修政、复制。通过分析,提出考试系统成绩的安全性管理的多级管理模式,每一级均起到一定的保护作用。多级的结合,使得考试系统的成绩有了一定的安全保障。该方案在实际考试系统运行过程中收到良好的效果。The grade of C/S based examination system is generally stored in the databases, which are distributed at different places. However, there are several security problems in such databases, such as modifying and copying grade easily. A multi-level management model of grade security is presented. In this kind of mode, every level provides certain protections and the combination of multi-level protections further security examination system's grades. The implementation of this model benefits a lot to the practical examination system running.
