Re: How many kinds of the data marts? and what are they?

Hello,

There are three kinds of Data-Marts (DMs), which are as follows:

1. Independent DM: Created from operational systems and have seperate physical data-store.
2. Logical DM: Exists as a subset of data warehouse. (build over data warehouse logically)
3. Dependent DM: Created from a data warehouse to a seperate physical data-store. (build over data warehouse physically)

HTH.

Regards,
