Given E(ABCDE) ABC are candidate keys

Normalize into 2NF and 3NF

As far as 2NF is concerned the solution is quite easy:

    E1(BD), E2(DE), E3(ABC) 

But with regard to 3NF I think I'm wrong if I say that nothing should be done?

I do apologize but I'm unable to work out how to normalize a schema into 3NF

Thanks a lot
