Data Mart

A data mart is a part of a data warehouse. A data warehouse provides information for business decisions. Data marts are decentralized storages of data and may be deployed according to the business departments' different informational needs. One distinguishes between dependent and independent data marts:

  • Dependent data marts are fed by the database of a data warehouse. This refers to the top-down architecture of a data warehouse.
  • Independent data marts are directly fed by the operational systems. Those are used when building a data warehouse using the bottom-up methodology.
