We Have the same issue here. Large Tables , loaded
nightly But nobody uses them. Management calls it a
Datawarehouse, I call it a data repository. Can a
cusotmer find out what they need. NOPE
Document your findings, to C.Y.A.
Good Luck

more important to report that you did something that

have to do is load data into a relational database
and give the end users a
point and click GUI tool is foolish but not uncommon
with shortsided
damagement.

I've lost patience, my temper, and I'm about to quit
a job because the IT
manager has decreed that we will have his data
warehouse running within
24 hours, and we will use his design.
1 - We are NOT to use any kind of views, not even
materailzed views.
2 - we are not to do any computations, summaries or
rollups
3 - we are to have everything in one table
4 - the table name and column names will be
meaningful to any clerk
5 - we are not to start or snowflake designs.
That's just a bunch of
high power talk.
6 - all users will be trained to use MS Access to
get at their
data. (These are users that were just converted off
from green screen
teminals within the last 45-days, to Windows 98 with
64k RAM.)
7 - We are not to just copy the legacy transactions.
8 - We are to load into an Oracle table, all
legacy transction data
because we don't want to limit how or what a user
will look at
9 - It is not necessary to talk with the users to
see what data they want
to look at, or the atomic level. They are smart
enough to fighure this
out on their own. We just need to provide them the
data.
10 - There shall be no long term maintenance
required by the dw.
Any ideas on how to deal with this situation?
For tomorrow, I've done a CTAS from a materialized
view that we created to
support one departments known requirements.
