A Data Warehouse (DWH) is a well-organized storage system that collects data from different parts of a business: sales, finance, or operations. It stores it in a structured way, ready for reporting and analysis. A well structured DWH is like a neat library where every piece of data is carefully labeled and stored in the right place.

Unlike a Data Lake, which stores raw and messy data, a Data Warehouse stores clean, processed, and organized data that’s easy to understand and use for business decisions.
