I heard someone said that if you do not need to know the intrinsic details of the database, then go for Oracle. I love Oracle because of its robustness. No database can compare against it. It has been there for a long time... Some other database that rose together with Oracle have already died down, but this database still lives.
Am I going to compare MySQL and Oracle here? Nope. For all you know, you really did not have a choice as to which database you have to choose. Your boss chose it for you. So, what is the point of having a title called 'Oracle vs. MySQL' if I'm not going to compare them? Nothing really. It's just a point where there are certain things in life that you really don't have control about.
