The "standard" answer would be "educate yourself". :-) I don't know how "precisely" you want me to be. I would say that my current understanding of this (because I have not yet read Codd's 1990 book - which I strongly recommend because I browsed it) is that domains do not include any kind of operator. What is your opinion ? Received on Mon Jun 05 2006 - 06:39:34 CDT
