摘要
本文首先结合数据仓库的建设目标,提出了在系统规划时可以采用的若干总体性能指标。然后,依据业界两种主流数据仓库设计思想,对带有ODS的数据仓库逻辑架构作了描述;接着重点对各种主流数据仓库平台进行了对比;最后从技术规范的角度在数据仓库性能评价方面提供了若干参考建议。
Firstly based on the targets of building a data warehouse （DW）, some overall performance indices are put forward. Then, according to two DW design methods, a logical architecture of DW with ODS is described. Then several mainstream data warehouse platforms are compared. Finally, from the perspective of technical specifications, a number of recommendations on performance evaluation of DW are proposed.
