Anybody know a good place in Dallas that teaches Oracle or SQL for DBA? If so please let me know.

I use SQL/Oracle and VFP but would like to know more about the DBA's view of it. We have a small office here with only one so called DBA and he is not here half the time. I volunteered to become the "real" DBA. Well, anyway, if you know please let me know, I'm eager to learn.

Thanks a bunch
