基于属性关联的关系数据库推理审计方法

传统的审计方法解决了一般的推理审计问题,但是在审计的中间阶段没有考虑依赖关系中数据的可用性,从而会产生较多的冗余审计。该文针对多级安全数据库的推理审计问题提出了一种采用基于属性关联的方法,解决了基于FD的推理审计问题,并且解决了在审计中间阶段造成的数据冗余问题,通过进行优化提高了效率。

Inferential Audit Method of Relational Database Based on Associated Attributes

Traditional audit methods have solved the general inferential audit problems.But data availability with dependency relationship was not taken into account in the middle stages of the audit,so that a large amount of redundant audits arises.In this paper,the method specific to inferential audit in multilevel relational database is raised based on associated attributes,which solve the inferential audit problem based on FD and the data redundancy in the middle stages of the audit.And the optimization brings hig...
