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.

Key words: data cube, online analysis process (OLAP), security strategy
