A _____ is a subset of a data warehouse that is used by small- and medium-sized businesses and departments within large companies to support decision making.

A data mart is a database focused on an area that is often an isolated segment of an enterprise data warehouse. The subset of data contained in a data mart is usually aligned with a specific business unit, such as Sales, Finance or Marketing. Data marts accelerate business processes by giving access to information in a data warehouse or operating data store in a matter of days, not months or longer periods. Since a data mart only contains the data applicable to a specific commercial area, it is a cost-effective way to obtain exploitable information quickly.
