In Business Intelligence, usually we talk about three areas: Database and Datawarehouse design, ETL, and Reporting. We covered the first one, and are now we are just ahead of starting the second one. In this ETL chapter we will see how to Extract, Transform, and Load process the data into our datawarehouse. Let's start!doi:10.1007/978-1-4842-2568-4_6Albert Nogu...
Yet, with reverse ETL, this process is flipped backward. First, the data is extracted straight from a data warehouse like a cloud server. Then, instead of transforming the data on a secondary processing server, reverse ETL transforms it within the warehouse it’s sourced from. Data warehouses...

Because you might not know the workload of your data warehouse in advance, you must optimize the data warehouse to perform well for a wide variety of possible query and analytical operations. Are updated regularly (nightly or weekly) by the ETL process, using bulk data modification techniques ...
