Consider the following dependencies in a database
D → A A → E
N → R R → N
C →  C → I
(R, C) → G
The relation (R, N, D, A) is
  • a)
    in BCNF
  • b)
    in 3NF but not in BCNF
  • c)
    IN 1NF but not in 2NF.Correct Answer
  • d)
    None of these
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Consider the following dependencies in a databaseD → A A → E...
D →A A → E
N →R R → N
C →  C →I
(R, C) →G
From the given relation
R( R, N, D, A)
The functional dependencies which this particular relation hold:
D →A N →R R → N
The candidate key for the relation will be: RD, DN
Hence partial dependency exists in the given relation R:
D →A
So relation is in 1NF but not in 2NF.
