I've heard “DWH” referred to as data warehouse in
data lake vs DWH. A data lake allows for raw data to be stored in its original format, a DWH is designed to store processed and structured information for reporting and analytics. They are not "all the same" as each one is solving a different problem. Knowing when to use each one than choosing one way over the other is more important if you are planning a modern data platform. Datalance offers real-world examples to help make it easier to understand.
