Here, of course, you're assuming that such a magical GUI, sort of DBA in an ancient oil lamp, tools exist. Well, they do not. Even if you have some useful gooey tools, they do require extensive configuration and customization to become useful and they do require extensive knowledge from the person doing configuration and customization. Other then that, I find it quite questionable how useful it is to fire your own customers and replace them with cheap Elbonian labor. Anyone who has called Oracle support recently knows exactly what I'm talking about. On 12/08/2003 04:44:31 PM, "Orr, Steve" wrote: > No Bambi, > > No, no, no... This is not what damagement wants.
