In reply to yesterday's posting concerning the DeWitt benchmarks for DBMSs,
I got the following mail from Prof. DeWitt himself:

Actually,  the sigmod84 paper describes the multiuser benchmarks
there is a 1983 VLDB paper by Bitton, DeWitt, and Turbyfill
that describes the single user benchmarks.  These are the
ones that have become the defacto standard.  tapes of these
benchmarks are available from me for a nominal charge or
from anyone else who will make you a tape for free.  There
is no copyright on them

I don't read news groups so you might forward this on.

The full reference for this earlier paper is:

Bitton,D., DeWitt,D.J., Turbyfill,C.:  Benchmarking Database Systems -- A
Systematic Approach.  In Proc. 9th Int. Conf. on Very Large Data Bases, 1983,
pp.8-19.

By the way: The newest issue of Computerworld contains an article "RTI claims
Oracle DBMS tests were biased" following an earlier article a couple of weeks
ago which said that Oracle claimed their new Version 5 outperformed INGRES
Version 4.
