You are a bit vague in your question. I'll just give it a shot.

If you are looking for some working example, why not look at the everything core (see also link at the bottom of this webpage)? Or slashdot's?

By 'single file', do you mean single perl file? Why be obsessed with a single file? It's the functionality/ modularity that counts, not whether you can cram it in one file.

It probably is a good idea to hide an interface from your own core, as long as you do it in such a way that you don't force unhappy constructs in the calling code.

I personally think that a lot of the database management stuff you mention are just the problems that are solved by the RDBMs. If you don't like MySQL's solutions, try eg postgres or oracle etc etc.

Hope this helps, and good luck with your coding!
