MySQL was principally "just a data store". There was relatively little reliance on higher-end database functions, and performance was at a premium. The claim was also that transactional integrity was provided through OM itself.
\r\n\r\nThen again, I keep my salt-sack open when considering Rob's dictums. I've caught him at several times at really major fibs. E.g.: Linux doesn't do networking at runlevel zero, Molar volume is a (practically) constant number of molecules of gas at constant T & P. Given his background -- graduate biology w/ significant chemistry, and years of Linux programming and admin -- he really should have known these. Worst, he was insistant on being wrong.
