A word of advice: Never argue with a fool. People may not notice the
difference.
For months now, this group is filled with uneducated, ego-puffed idiots
like the ignoramus you are responding to.
Search google with "Daniel Morgan"+Cobb. It is hilarious, but pathetic
that someone who doesn't even know the inventor of the most successful
and theory oriented data model "contributes" to database theory. You
should see how he "guides and directs" newbies to learn normalization
in oracle newsgroups though :)
Some other trolls include Dawn, Neo etc who have nothing meaningful in
their lives, with only an axe to grind. Gone are the days when people
with a brain contributed to this group. Paul, Bob, Jan, Vadim, Mikito
etc. are all quiet, not sure why.
