什么是数据仓库？ [英] What is a data warehouse?

问题描述

我被客户问我们数据仓库是什么意思。

我考虑过ETL，数据模型的细节，与NoSQL，Clouds，'正常'DBMS，MDM（主数据管理）等的差异，

如何可以数据仓库描述

对于非技术人员，最好的是将其描述为

>存储在专用计算机系统中的巨大数据数据通常与某些特定领域相关，整个系统被设计为快速并针对某些特殊任务进行优化。存储在数据仓库中的数据主要用于分析或决策进程。

不知道这是否足够:)在互联网上有很多这个主题的引用，但如果有人问我一个快速定义我会使用类似于我上面写的那样。

I was asked by a customer what the term "data warehouse" really means.

I thought about ETL, details of the data model, differences to NoSQL, Clouds, 'normal' DBMS, MDM (Master Data Management) etc. but wasn't able to describe the term in a few words to him... (In fact I did some talking and left him un-illuminated.)

How can "data warehouse" described in 1-3 (or a bit more) sentences?

解决方案

For non technical guys the best is to describe it as "Huge ammount of data stored in a specialized computer system. Data is usually related to some specific domain and whole system is designed to be fast and optimized for some special tasks. Data stored in data warehouses are mostly used for analysis or in decision making processes."

Not sure if this is enough:) There is a lot of references to this subject in the Internet but if somebody asked me for a quick definition I would use something similiar to that I wrote above.
