Propuesta de Kimball

Kimball, in 1997, stated that "...the data warehouse is nothing more than the

union of all the data marts", Kimball indicates a bottom-up data

warehousing methodology in which individual data marts providing thin views into

the organizational data could be created and later combined into a

larger all-encompassing data warehouse.

Propuesta INMON

Inmon responded in 1998 by saying, "You can catch all the minnows in the ocean

and stack them together and they still do not make a whale," This indicates the opposing view that the data

warehouse should be designed from the top-down to include all

corporate data. In this methodology, data marts are created only after

the complete data warehouse has been created.
