And then came my opinion and God Knows if it is Good... ;)

After all 'know that u are eager for some (h)ope(i)n source ...
next step will be on linux because i no longer work for a windoze company
in my box there it is an FreePascal compiler with some interbase examples...
(www.freepascal.org if you need the pascalissimo)
in the future will do some perl examples also and some mysql to will enter the scene
these days u no longer need only one tool for the job
so my needs are increasing (more connections,more users etc...)
take a look at a great site they are not using interbase because it is
not known first and secondary it is limited to about 250 connections
so if you need something fast do the mysql (for loging users to your site etc... )
if you need something komPleX do the interbase (aka firebird)
Really like the *bird but is good for the low trafic sites
teke a look at slashdot.com they realy have a bussy site
so i opted to a middle solution with interbase as a management tool
and mysql for the web output baby
what about Kylyx ? don't know i have not seen it yet ...:o(
but i will learn more about it soon i have it..
