Data Marts

A data mart is usually a smaller version of a data warehouse, used by a single department or function. Data marts focus on business functions for a specific user group in an organization, such as a data mart for the Marketing Department. Despite being smaller, data marts can usually perform the same types of analysis as a data warehouse.

Data marts, however, usually have more limited scope than data warehouses. So, consolidating information from different departments or functional areas (such as sales and production) is more difficult.
