i have 6 attributes A,B,C,D,E,F
{A,B} > C,D,E,F
C > B
D > C

Best ResponseYou've already chosen the best response.1{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 nonprimary 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.

Best ResponseYou've already chosen the best response.0Have you normalized this to 2NF or 3NF ?

Best ResponseYou've already chosen the best response.1Heh, apparently I skipped directly to 3NF.

Best ResponseYou've already chosen the best response.0Ok thanks alot !! Could you please also tell the 2NF ?

Best ResponseYou've already chosen the best response.1I might have actually skipped the whole 2NF step =P give me a minute to analyze

Best ResponseYou've already chosen the best response.1Hm, 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.
