A data warehouse is a centralised storage facility for structured data. A data warehouse, as the name implies, is well-organized, with metaphorical halls of labelled shelves containing structured data sources (like SQL databases or Excel files). It's not a messy storage area with stuff heaped and piled in an unorganised manner. Anyone who has ever gone hunting for their golf clubs in a cluttered garage only to discover them hidden among the Christmas decorations understands the benefits of a well-organized data warehouse.
