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