I receive emails that say -
'I am an Oracle DBA and I have just been laid off, what do I do ?'
The implication is clear - if you are in this position, you should acquire
some DBA-related skills which give your CV a broader appeal, such as Database Developer, which brings us to ...
The second most common occupation would be as a Database

This is also
the conclusion on January 4th. 2004, of the respected Oracle expert, Tom Kyte.
Oracle continues to be the market leader, at 33%, although
IBM's DB2 is close behind at 31%, but Oracle dominates
on UNIX, whereas IBM is dominant on mainframes.
Microsoft's SQL Server is way behind at 14%

Integrated Compliance Framworks and Generic Data Architectures.
