WHAT i feel?

I have looked into what are database is all about, what is database administrator is required to do, and oracle, an exam compulsory for all database undergraduate, as far I am concerned. I thought to myself, why didn't I know anything about this before I enrol into this course. Even when I applied for this course, I actually didn't know what database is all about, all I know it sounds NEW and INTERESTING. Now the question is, is it my fault of not knowing what database is? or is database not promoted well in our country?
