I've made many researches about data warehousing to learn more about it and I think I've grasped the idea. But I've read in an article or two that data warehousing allows you to do analysis on data brought from operational databases and then in some cases, the results are sent back to the operational databases where some data is updated and then used.
Could someone give me an example where that might work?
Because what I personally understood is that data warehousing allows to analyse the data in order to determine sales profitability or find patterns in sales, etc.
So is what I've read true? If so, are there examples?
