Oracle is only run on the Solaris servers. MYSQL on both.
So, how do you compare MYSQL running on Windows compared to SQL Server? ( What versions of MYSQL and SQL Server are you guys using anyway?)
I believe the article is showing an increased market share for SQL Server because it has been designed and dedicated to the Windows platform.
Like it or not, Windows has over 90% of the OS market worldwide and Microsoft’s dominance in this area will simply ensure that any product they develop, be it Database Servers or Web servers or browsers will be OPTIMIZED for the Windows platform ( whatever version they’re coming up with ).
