I would think it more accurate if you use the phrase "faster for
simple SELECT queries."
MySQL uses a rule-based optimizer which, when the data fits the rules
well, can pump queries through lickety-split without any appreciable
pause for evaluation (or reflection :-). That's _quite_ a successful
strategy when users are doing what loosely amounts to evaluating
association tables.
select * from table where key = value;
Which is just like tying a Perl variable to a hash table, and doing
$value = $TABLE{$key};
In web applications where they wanted something a _little_ more
structured than hash tables, that may 'hit the spot.'
Anything hairier than that gets, of course, hairier. If you want
something that's TRULY more structured, you may lose a lot of hair
:-).

"If you want to talk with some experts about something, go to the bar
where they hang out, buy a round of beers, and they'll surely talk
your ear off, leaving you wiser than before.
If you, a stranger, show up at the bar, walk up to the table, and ask
them to fax you a position paper, they'll tell you to call their
office in the morning and ask for a rate sheet." -- Miguel Cruz
