Hello,
I need some facts on how MySQL compares to an AS/400 with their
integrated data base engine. I'm talking to an AS/400 user who
claims that there is no software in the market that can hold up
against the AS/4000 in terms of speed and reliability. One
claim is that it didn't fail him once in 15 years, and speed
is also very impressive. On his regular used system, one of the
smalles AS/400 you can get, serving some 1-3 GB of data (he
didn't know exactly how much, but 1GB is the absolute minimum
we estimated from one table), he ran complex reports that
involved from several hundred thousand records to a million
records in some 1-5 seconds wall clock time. Hard to beat that,
I say, but first we need to get the chance ;) We would
need to serve the same data from a PC server running Linux,
but with a web frontend instead of a tty front end. He doesn't
trust MySQL to be sufficiently reliable and fast, and I
have no facts to match his claims. The task would be to
process all kinds of sales figures, orders, and some
manufacturing data, too, for MIS reports and possibly data
entry frontends to the legacy systems. So his question is
how high is his risk to loose by investing into development
for a prior-known unsuitable "solution", while we think it's
feasible to go with MySQL but lack the hard facts to back
this up. www.mysql.com gives too little evidence of what
is actually needed.
A related issue would be how to connect the two data base
engines together, so that importing or re-exporting the
data from/to the AS/400 goes smooth. Perl would be the
language of choice here ;)
