A data mart is the central storage area for the knowledge resources of a particular department or user community. A data mart contains both derived and raw information - the source of that information being the corporate database or data warehouse. A single organization may have many data marts.
A well-designed data mart meets the specific needs of a particular group of knowledge users. For it to be effective, a data mart must be optimized for analysis, content, and ease-of-use, thereby helping people strategize through the use of past trends and comparative analytics.
To populate and maintain a data mart, a particular set of information must be extracted from the larger data warehouse, transformed into meaningful forms, and loaded into the data mart - processes which require considerable time and computational resources. This is where superior tools and technologies play a valuable role.
