多维数据访问监视器的设计与实现

The Design and Implementation of Access Monitor for Multi-Dimensional Data

为了在数据仓库系统中跟踪、评估对多维数据的访问,提出了一个访问监视器的概念.通过它可以实时监督系统中正在发生的多维数据操作,并能根据需要强制终止访问会话.此外,该监视器能够将详尽的历史记录保存起来,可用于对访问控制做进一步的分析处理.

In order to track and evaluate the access to multi-dimensional data in data warehouse system, this paper proposes a concept of Access Monitor. Through AM, various operations on multi-dimensional data can be supervised in real time, and suspicious session can be terminated mandatorily on demand. In addition, this utility keeps detailed historical access log which will be used in further analysis processing on access control.
