数据仓库中的暂存步骤?
人们通常如何执行数据仓库中的暂存步骤?
我必须做类似的任务,我不确定使用 NoSQL 数据库是否是数据集成的一个不错的选择,以及执行数据清理和清理有多容易和高效
有人在这方面做了一些工作吗?
请让我知道,
对于一个通用问题表示歉意,但没有想出比 SO 更好的地方来问这样的问题,
谢谢
How do usually people perform staging step in Data warehousing??
I have to do a similar task and I am not sure if using a NoSQL Database would be a good option for data integration purposes and how much easy and efficient would it be to perform data cleansing and scrubbing
Has someone done some work in this area?
Please let me know
Apologies for a generic question, but didn't come up with a better place to ask such question than SO
Thank you

对于数据清理和 ETL,您需要可以获得最丰富的查询功能,但这通常不被视为 NoSQL 数据库的优势。在大多数情况下,您可能更适合使用传统的 RDBMS 平台作为数据仓库系统。
For data scrubbing and ETL you want the richest query facilities you can get, which is not generally regarded as a strength of NoSQL databases. In most cases you're probably better off with a conventional RDBMS platform for a data warehouse system.
对于暂存区,您可能需要一个强大的 RDBMS 平台。我已经使用了 Teradata,它是迄今为止最好的 RDBMS 之一,因为它允许并行执行查询,并且具有非常高的性能。
For Staging area you might need a strong RDBMS platform. I have used Teradata for it and its one of the best RDBMS available till now as it allows parallel execution of queries and it has very high performance.
