RE: What is a "database"?

["Martin, Booth" <BoothM@xxxxxxxxxxx>]

The best one that I heard is that data mining showed a correlation between
diaper sales and beer sales.  In an experiment to laughingly disprove the
relationship the company made a stack of their highest margin beer at the
end of the diaper aisle.  Over the period of the trial they discovered their
over-all beer sales didn't increase but their product mix changed to reflect
increased sales of their high-margin beer.

Data Mining is a new concept.  Data Mining looks at data in
a different matter than a simple data base.  Say, for instance,
you have all your sales in a file (most people do).  You also
have your vendor file, and the dates.

You now look at your data by dates, say, and see that a
certain product sells 25% more during a certain 3 month period
then any other months.  Looking for a correlation you see the
months are November, December and January.

By data mining you can, as administration, say you need to stock
up on umbrellas 25% more during the winter months <g>

Stuff like that.  I don't think the title should apply to a programmer,
though, as that's not really what programmers do.  Do they ever
get titles right?
