I recommanded that programmers who often use the DB as their utils should study the Postgresql database. Maybe it makes you feel wonderful!
If you want to learn this database,you can download the sam's postgresql book in the Internet or in my blog,it's a good book to start to learn thd postgresql. The official docs is also a good reference. http://www.postgresql.org.
