半自动化构建的大型数据仓库体系结构

Half Automatization of the Architecture of Large Data Warehouses

传统的数据仓库 (DW )体系结构在对大量异构数据源进行操作时 ,会暴露出许多不足。本文章提出了一种改进的三层体系结构的数据仓库模型 ,并给出了在此模型基础上数据仓库的半自动化构建方法。

Classical system architectures of data warehouses sho w some drawbacks when they are applied to the work of large numbers of heterogeneo us operational sources. In this paper we propose a improved three-level architec ture for data warehouses that overcomes these drawbacks. In this paper Semi-auto matic techniques are also illustrated. The techniques are capable to produce the data warehouses which are designed according to the proposed architecture.
