摘要： 在分析数据立方体中信息维层次结构的基础上，提出一种基于数据立方体维层次的OLAP安全性策略。结合维层次信息设计安全访问规则，不仅使得安全策略易于实现，而且能更有效的支持各种OLAP操作。理论分析与实验证明，这种安全性策略具有描述能力强，管理简单，执行效率高等特点。

Abstract: By analyzing the hierarchical structure of information in a data cube, security strategy of an online analysis process (OLAP) based on dimension and hierarchy of data cube is proposed. By combining the visit rules with the information of dimension and hierarchy of data cube, the security strategy is easily implemented, and can support OLAP operations more efficiently. Theoretical analyses and experiments show that this security strategy has powerful description ability, simple management and high execution efficiency.
