 A data warehouse stores current and historical data of potential interest throughout a company. Data warehouses gather data from multiple operational systems inside the organization. Data warehouses make data available, but do not allow that information to be altered. Data marts are subsets of data warehouses, in which a highly focused portion of an organization's data is placed in a separate database for specific users. Data marts are decentralized, whereas data warehouses are enterprise-wide, central locations for data.
