摘要
分析了目前数据库系统安全机制及存在的问题,提出了一个混合动态安全管理模型,并对模型的体系结构及模型构造算法作了详细地描述,探讨了该模型的实现技术,为数据库应用系统开发者提供了一种灵活基于操作的数据库系统安全设计方法。
A mixed dynamic security management model is presented by analyzing current security mecha- nism of database system, and then the model structure and the model construction algorithm are described in detail. Furthermore, the realization technology of the model is discussed, which provides a flexible design method based on operation database system security for database application system developers.
