Where can I read something about MySQL compared to Oracle? I have very little 
experience in the database world but what I heard about Postgres is that they 
make the competition to Oracle, they are like the Open Source alternative to 
big enterprises. The question is where is MySQL? Do they compete with MsSQL? 
Is MsSQL a big enterprise database engine (I heard the opposite, the are for 
small business or enterprise)? Are there URLs?
