Hi,
Anyone have experience of installing Perl on Irix 5.3? I'm sure there are
lots of good reasons for not even beginning to attempt this but putting that
to one side...
The latest I have on the machine, an Indigo, is 5.004 from

The first few advantages that come to mind:
It scales. :D
It supports (several varieties of) transactions.
It can write internally consistent backup dumps.
It supports write-ahead-logging
I like the idea of this:

have databases which fit in memory. I mean, otherwise they'd be in

It's a curious idea shrouded by great mountain ranges of bombast.

No, they're too dumb for that - but a company called InnoDB basically
re-wrote the core parts of MySQL and called it a "storage back-end".

Is that the NZ stock exchange that crashed recently because of a

Hi,
As a Perl beginner who has realised I need to set up a database, I have to
add that I immediately went for MySQL due to all the attention it seems to

compares favorably to PostgreSQL, and it can be easily embedded.
