So, you have no bottlenecks, no goals (performance wise), you're rather small, and all you can tell about your future is that you're adding "canned applications, along with my custom coding".
Yea, you're correct.
What do you expect to get?
Your advice. Tell me what you do or would do as a programmer if you had complete control over your db server. Are there any practices you yourself follow? Of course, we all use strict. Do you have similar rules you follow and/or made in regards to sql db interaction? Do/would you develop your sql from your perl or instead put it outside on the db server? And what are your reasons for doing it that way?
