1. ODS is close to the source. We can say it is a replica

While the staging area is a replica of the target DW.
2. The dimention and fact will come into picture here in
staging.
3. We are doing the Transformations in staging schema
before loading it to the target.
4. We integrate different ODS source systems into the
staging area and not in the ODS.
