摘要： 常规的数据仓库应用中，分析和决策较多地依赖于用户参与。为了在自动决策以及实时性等方面对常规的数据仓库进行改进，文章设计了一种主动数据仓库（Active Data Warehouse）体系结构。它在常规的数据仓库的基础上引进了分析规则。通过对主动规则的改进而设计的分析规则能满足主动数据仓库的特性。相应地还对数据仓库的元数据进行了扩展。

In order to make data warehouse automatic and real-time, a improved architecture with analysis rules棗active data warehouse is designed . The analysis rules is provided by extending the active rules in active databases. Metadata is also extended .
