The data warehouse, unlike the other IT systems in an enterprise, is an exclusive data platform with a data model as its backbone. In general, one may conceive an IT system to be a combination of processes and data. However, the data warehouse is only about data, and even the processes within a warehouse are data-centric. This trait of data warehouses prompts different vendors, big and small, to develop data models for every industry (called "industry data models") as a standard offering to decrease the turnaround time in developing data warehouses.
