What is Data Mart?

Data mart is a database that contains a subset of data present in a data warehouse.

Data marts are created to structure the data in a data warehouse according to issues such as hardware platforms and access control strategies.

We can divide a data warehouse into data marts after the data warehouse has been created.

Data marts are usually implemented on low-cost departmental servers that are UNIX (or) windows/NT based. The implementation cycle of the data mart is likely to be measured in weeks rather than months (or) years.
