基于元数据的数据仓库安全模型实现研究

Research of implementation for data warehouse security models based on metadata

元数据是数据仓库的关键技术之一,也是数据仓库安全性的解决途径之一。对基于元数据的数据仓库安全模型进行了研究,对原模型进行了改进,并提出了在Oracle9i数据仓库平台上的解决方案。

Metadata is one of the key technologies in the data warehouse, and it is also an important way to solve the security problems. This paper gives a deep survey on the data warehouse security models based on metadata and extends the ruction of the original model, and gives a solution on Oracle9i.
