Jared,

Yeah, they don't want to hear about PL/SQL because then they can't scale it up on the middle tier where they can have dozens of machines with the same poorly written app simultaneously pounding the database thousands of times more intensely than the task requires....

Hmmph. Topics like this on a Friday make me want to dig deeper into my toolbox (the malted compartment of course).
