[HELP] between the CO private to connect using Database. [v5165]

[sex13]

using this guides: it works successfully, but my questions are..

1. How can i connect the CO server to database, like using xampp, appserver, postgresql etc. most i have read they using appserver, but the tutorial is incomplete.

2. Secondly, how can connect between the webserver(register page) to database of the CO?

3. Can use free domain in order to run the server( what i mean is i will make a register page there directly to my database)?

may be you can solve or link any existed tutorial of it.
sharing is loving, if you can solve this everybody can solve there problem too somehow.
