数据仓库安全模型研究与设计

随着数据仓库的发展，安全问题日益突出，一方面数据仓库本身需要足够的开放性，另一方面数据仓库的数据价值很大，要求对数据仓库用户加强数据访问的限制。开放与限制，两者的矛盾会严重制约数据仓库使用。论述了数据仓库安全问题产生背景及安全模型的重要性，针对数据仓库的安全问题提出安全模型。该模型能够减少数据仓库会出现的安全问题，为企业进行数据仓库设计提供参考。

Security model for data warehouse

With the development of data warehouse, the security problem is becoming more and more serious. On the one hand, the data warehouse itself needs enough openness. On the other hand, the data warehouse is of great value, which is required to strengthen the restriction of data access for the users. Opening and restriction, the contradiction between the two will seriously restrict the use of data warehouse. This article discussed the background of data warehouse security and the importance of security model, put forward a security model for the security of data warehouse. The security model could reduce security problems and provide a?reference for the design of data warehouse to the enterprise.
