147.0. "DeWitte Benchmark / ORACLE" by DUB01::POCONNELL () Mon Jun 13 1988 12:23

Has anyone come across the DeWitt Benchmark. A prospect who has
decided on ORACLE requires that the sort-listed suppliers,
Digital( Microvax 3600), H.P(820 Unix) and IBM (6150 under AIX)
run the above mentioned Benchmark. 

Information on this or on performance comparisons would be much
appreciated.

147.1Beginning...CREDIT::BOOTHA Career in MISunderstandingMon Jun 13 1988 16:078
    The DeWitt-Wisconsin benchmark was developed to establish the need
    for database machines. It is geared to producing results that force
    the database machine to be considered. Normally, Oracle and Ingres
    are the big "pushers" of that benchmark. If I remember correctly,
    it is not very weighted for update activity. More emphasis is on
    querying, lots of selects...

    BITTON, D., DEWITT, D.J. AND C. TURBYFIL, "Benchmarking Database
    Systems: A Systematic Approach," Computer Sciences Department Technical
    Report #526, Computer Sciences Department, University of Wisconsin,
    December 1983.  This is a revised and expanded version of the paper
    that appeared under the same title in the Proceedings of the 1983
    Very Large Database Conference, October, 1983.
    
    Boral, Haran and DeWitt, David J., "A Methodology for Database System
    Performance Evaluation," Computer Sciences Dept. Tech. Report #532.
    This research was partially supported by the National Science
    Foundation under grant MCS82-01870 and the Department of Energy
    under contract #DE-AC02-81ER10920.
    
    Basically, the first report explains the reasons for using a
    a simple, stand-alone database system to begin benchmark developements.
    The second article expands on that study into a mutli-system
    environment.  Also, the second article highlights the key techniques
    and strategies that ought to be covered in the study.
    
    I'll dig up the article and write an article report.
