Each Data Warehouse may differ in their size, scope, or complexity, there are certain fundamental themes that they all share.

The three important themes that all data warehouses share are -
  • Processing time (Or) Handling Time
  • Drilling down
  • Drilling up

If a system has all of these factors, and it runs with a high level of efficiency, it can be truly called a data warehouse.
