ABSTRACT
Introduction A data warehouse is an asset of an enterprise and exists for the benefit of an entire enterprise. It does not exist for the benefit of a single entity (e.g., business unit, individual customer, etc.) to the exclusion of all others in the enterprise. As such, data in a data warehouse does not conform specifically to the preferences of any single enterprise entity. Instead, a data warehouse is intended to provide data to the entire enterprise in such a way that all members can use the data in the warehouse throughout its lifespan.
