Yes and no: yes, I made it through a military bootcamp in 1965, but no, it was not one for DBAs. There were no DBAs back then. 🙂

No, I do not think that a DBA bootcamp would be useful. The problem is that the database world is changing faster than the military world, and I doubt that any program pre-planned and sufficiently marketed program would produce graduates that have the skills required by the time when they hit the market.

I mean, who feels qualified to design, in this July 2011, a bootcamp that would produce graduates with skills in demand in May 2012?

Yes, there are the "eternal truths," such as "Back up the database before you tweak it," but you do not need a bootcamp to teach those.
