Newbie just started this week and went changing hibernate settings on us. Changed hbm2ddl from update to create, which nukes the data on every deploy. She thought she was working against her local DB when in fact she was pointed at the shared integration database, thus nuking INT. Through a couple hours of PL/SQL wizardry, I managed to resurrect the data. Within 5 minutes of giving the team the all clear, the data disappeared again...betcha can guess what happened...again!
