I've seen people write Perl code that fetched rows one at a time.  It's
relatively trivial to bind a database query in Perl so that large
fetches are done which greatly improve performance, and lower network
chatter too.

For that matter, much of the time you don't really need an SQL server.
Flat files, especially indexed, are almost always faster than using SQL.

My suggestion for one big shop was to covert *back* to batch processing
of data files, and use an SQL server that was updated every 24 hours for
ad-hoc stuff.

Most people cannot understand that you rarely need realtime access to
data, especially financial data.  In fact, most of the time not limiting
your queries to dated ranges is an error.

Years ago a suit came to me complaining that our reporting software
was broken.  He showed me two reports that had different answers in
the summary.  I had to explain to him that during the day transactions
occured every few seconds, so the answer would likely be different for
every report if run on the current day.

I also had to tell him that his queries were wrong, since he was only
supposed to look at data from the last and smallest fiscal period, which
for this company was bi-weekly.

He had an MBA.

I wish colleges still taught things like that.  I'd love to go back and
work on a project like that.

I think I learned more working on timesharing systems than I ever
learned working on a personal computer.
