Eat SQL for breakfast? We have a challenge for you.
The DB-Quest Challenge is now out there in an effort to document the identities of the smartest database professionals, globally. (You know who you are.) The questions range from the easy to the difficult, with some being designed by Oracle ACEs (thanks to Andrew Clarke, Bradley Brown, and Dave Moore). So, if you think you can correctly answer questions on a range of database management-related subjects, then this is your opportunity to join the Global Top 10 leaderboard.
Brainiacs who reach the leaderboard earn the privilege of submitting new questions for inclusion in the quiz. Even so, if you have a question to include and garner the overwhelming support of the community via this Oracle Mix group, we'll consider it too.
I'll be following the status of the leaderboard and reporting the results here from time to time. Give it a spin.
