Re: Datamart

Data mart is a special purpose subset of enterprise data for a particular function. It may contain

detail or summary data or both.

Data mart types:

Independent- created directly from ods

Logical- A subset of existing dw

Dependent- created from edw.

Hope it helps you. You can go through documents available.
