摘要
数据仓库是支持管理决策过程、面向主题、而且随时间变化的数据集合，它是集成的，也是稳定的。与其相比，数据集市则是更小、更集中的数据仓库。数据挖掘是采用人工智能的方法对数据库和数据仓库中的数据进行分析、获取知识的过程。文章对这些数据库新技术做了介绍，并且根据电力系统的特点、结合电力市场的发展趋势，探讨了它们在电力企业中的应用现状和前景。
A data warehouse is a decision supporting, sub- ject-oriented, assemble, stable and time-dependent collection of data, comparing with data warehouse a data mart is a smaller and centralized one. Data Mining is a data-analyzing and knowledge-acquiring procedure by use of artificial intelli- gence. These new database technologies are introduced in this paper, their application achievements in electric power enter- prises are analyzed, and the current situation and prospect of applying data warehouse and data mart to electric power en- terprises are discussed.
