Oracle 10g Express edition
DB legends are releasing their edition as a miniature, previously MS-SQL came with their own mini server. MySQL is always small doing great jobs. and Here I am giving Oracle 10g Express edition. It is cool, very easy to install and get it running. Add to its great things, It offers a cool web interface (see the screenshot below), like Linux admin tools 
. Oracle says it is free to develop, deploy, and distribute. Those who are interested can get their copies at
