Popular databases on SuSE and Red Hat
 

Can anyone direct me to a website or a source which can rate the following databases by popularity on Linux distributions such as SuSE and RedHat?

Oracle 8i or 9i
Sybase ASE
My SQL
DB2

Thanks in advance,
Shyamal.

perhaps this is a bit too late.
I remember reading recetly (at IDG) that by market share the DBs are like:
Oracle 39%
DB2 34%
MS SQL Server 11%
SYBASE 3.5%
Informix + mySQL + PostGreSQL + Interbase + ...= rest.

If you stick with Sybase 11.9.2 you can install on any linux that has RPM.
Oracle and DB2 are way too fussy and so is Syabse 12.5.
Sybase is becoming irrelevant now.

MS SQL server is the FASTEST growing DB out there. If alone MS can port it to Unix/Linux they can do even better.
