A data mart is a subset of data warehouse that is designed
for a particular line of business such as sales, marketing,
finance, etc.
Data mart is of two types:
1) Dependent data mart, in which data can be derived from
an enterprise-wide data warehouse.
2) Independent data mart, in which data can be collected
directly from sources.

Answer / poonam kute
Data Marts is used on a business division/department level.
A data mart only contains the required subject specific
data for local analysis.
A database, or collection of databases, designed to help
managers make strategic decisions about their business.
data marts are usually smaller and focus on a particular
subject or department. Some data marts, called dependent
data marts, are subsets of larger data warehouses. A data
mart is a simpler form of a data warehouse focused on a
single subject (or functional area) such as sales, finance,
marketing, HR etc. Data Mart represents data from single
business process.

Answer / sid
In the industry when a organisation goes for a enterprise
wide Datawarehouse the cost involved in setting up . its
maintenance and other overheads are also associated with
it. So due to budget and time constraints some
organisations initially set up a Data Mart to facililtate
there immediate needs . These Data Marts are generally set
up at department levels and in a future date if utility
arises then datamarts across the organisation can be
integrated and a full fledged data warehouse can be formed.
In a way Data Mart is a subset of Data Warehouse.
