摘　　要：数据仓库安全模型及访问控制技术随数据仓库应用的推广而变得重要。首先通过对RBAC模型(Role-Based Access Controlmodel)进行分级安全的扩展,并将模型应用到数据仓库的访问控制机制中;通过数据仓库结构模型的形式化描述,建立基于角色的数据仓库分级安全基础模型、分级安全配置模型,以及数据仓库分级安全模型的一致性检测算法。指出下一步的研究工作是分级安全策略与OLAP操作,扩展MDX查询语言,真正实现数据仓库分级安全应用体系。Security model and access control technology of data warehouse become the important issues along with the promotion of data warehouse application.In this paper,we first expand the RBAC（role-based access control） model in its hierarchical security and through this we apply the model to data warehouse access control mechanism.Secondly,with the formal description of structural model of the data warehouse,we set up basic model and configuration model of the hierarchical security for role-based data warehouse,as well as the consistency checking algorithm for the hierarchical security model of data warehouse.Finally,we point out that in the next step of our research work,we are to focus on the hierarchical security strategy and OLAP（online analytical processing） operation,the expansion of MDX query language,and the actual realisation of hierarchical security application system for data warehouse.
