摘要
介绍运用数据仓库的几个关键特性和ETL技术,构建银行系统数据仓库的过程。并提出了在构建过程中对处理阶段的划分方法和一些处理方式,以便当数据模型变动时,避免大规模修改仓库的构建。
The process of building the banking warehouse with some key attributes of the data warehouse and the ETL technology was introduced. Furthermore,some methods about how to divide the whole process and some relevant processing ways during building a data warehouse were proposed. Eventually,a mass modification of the architecture of a data warehouse can be avoided when some changes of the relevant data model happen.
