Yes , it is possible to create a datawarehouse without
using ETL tool. but it will be very very complicated and
time consuming and if the needs change you need to re-work
on it again.but when you use etl tools you can adapt you
can make the changes as required.

Answer / zak
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.
