Data warehouse is an environment that represents the organization’s data. Data warehouse gives a complete view of the enterprise - current and historical information for decision making.
A data mart is defined as the subset of the organization data. It includes explicitly analytical data of a particular subject or department in an organization. A data mart is of three different types:

1. Dependent
2. Independent
3. Logical data mart
