Theoritically speaking Yes. Preparing a Datawarehouse and
maintaining will only be feasible when the amount of Data
you are dealing with is small. Practically Datawarehouses
will have huge data with large number of tables and complex
business rules which may keep changing from time to time.
All this makes practically impossible to implement DWH just
by writing database queries.
