Data Warehouses and Data Mining

Example: Facebook

Example of data warehousing that everyone can relate to is what Facebook does. Facebook gathers all of your data – your friends, your likes, and so on – and then stores that data into one central repository. For many reasons, they want to make sure that you see the most relevant ads that you're most likely to click on, they want to make sure that every friends that they suggest are the most relevant to you, keep in mind that this is the data mining phase in which meaningful data and patterns are extracted from the aggregated data.
