{A,B} -> C,D,E,F C -> B D -> C {B,C} ->E It's been long since I've normalized tables. I believe this would be 2NF, since this eliminates all dependencies to non-primary attributes among the tables. _AB_ D F --D and F only depend on primary key _AB_ _D_ C --C only depends on primary key _D_ _BC_ E -- E only depends on primary key _BC_ I would suggest you check this, since I'm not really sure.

Have you normalized this to 2NF or 3NF ?

Heh, apparently I skipped directly to 3NF.

Looking for something else?

Ok thanks alot !! Could you please also tell the 2NF ?

I might have actually skipped the whole 2NF step =P give me a minute to analyze

hehe ok :)

Hm, I believe that's 2NF which coincidentially happens to be in 3NF aswell. Sometimes tables in 2NF automatically become 3NF. But again, maybe you should check this answer.
