Open Source Database Rankings

P: n/a
Does anyone know how the open source database rank in terms of deployments
and users worldwide? I saw something today
(http://story.news.yahoo.com/news?tmp...c_cmp/17200310
) that had SQLServer at 1, Access at 2, and MySQL at three, with no mention
of PostgreSQL. Seems to be flawed to me as the last time I heard both DB2
and Oracle were ahead of SQLServer in commercial rankings.

In terms of market share, measured in revenue from RDBMS licenses sold,
you are correct (assuming Gartner is correct), as of 2002:

But then again, SQL Server may cost 33% the price of an Oracle license
and find its way into more hands. So although Oracle has a larger market
share in license revenue, there may be more SQL Server installations in
existence. A more interesting figure would be the total number of
transactions, worldwide, running against each vendor's database. From
pure speculation, I'd guess the average number of simultaneous
transactions thrown at an Oracle or IBM installation at any
point-in-time is larger than the average thrown at SQL Server. But I
somehow suspect that figure is a bit more difficult to acquire.
