All I can say is

GOOGLE IT!!!

I get most of my coding questions answered via google. You might want to take a dba course, you can find them online as well.

Cheers!!

All of the SQL servers, Oracle, MySQL, PostgreSQL, DB2 etc will cover your 5 questions, with a positive answer.
PostgreSQL is the least encumbered license.
Oracle, DB2 and MS SQL Server are all comercial.
MySQL is somewhere in between.
IBM just released Informix to the Apache software foundation. That might be a good choice.
I recommend MySQL to learn on then switch to a license you can live with to set up your site.
Try Apache Triad to get a good learning enviroment

try this URL for basic knowledge. it maybe helpful to you.
Try this website (http://216.239.41.104/search?q=cache:q7L2nm062ZYJ:nsu-cc.northern.edu/mis/mis484/notes/ch10.ppt+Internet+Database+Systems+centralized+sys tem+vs+distributed+system&hl=en/)

I thought that was Cloudscape they released. There also seems to be a question over the licensing according to Groklaw -- or some kind of confusion between what IBM is saying publicly and what they actually told the NY Times. So far I have not seen any news about it at Apache.org yet.
