Oracle vs. SQL Server – a never ending story

11.1 vs. 2008

or

10.2 vs. 2005
http://psoug.org/reference/sqlserver.html

but always two things to keep in mind;

- Oracle is not cheap and getting more expensive with its new options on recent releases.
- SQL Server is cheaper but does not run on any other operating system but just Microsoft platform.

so why not going after another path :)
