A given relation is known to be in third normal form. Select the statement which can be inferred from this
  • a)
    All attributes contribute to the primary key.
  • b)
    Each non-key attribute determine the primary key.
  • c)
    Each non-key attribute is determine by the primary key.
  • d)
    Every determinant is a candidate key.
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
A given relation is known to be in third normal form. Select the state...
A relation is in 3NF if for X →A
(i) X is a super key or candidate key
(ii) A is a prime attribute.
Hence, for A to be non-key attribute (non-prime attribute)
X must be satisfying (i)

A given relation is known to be in third normal form. Select the state...
Explanation:

Third normal form (3NF) is a database normalization technique that ensures that the data is stored in a way that prevents data redundancy and inconsistencies. In 3NF, every non-key attribute is dependent on the primary key. This means that:

- Each non-key attribute is determined by the primary key
- No non-key attribute is determined by another non-key attribute

Therefore, the correct statement that can be inferred from a relation being in 3NF is that each non-key attribute is determined by the primary key. This means that the primary key uniquely identifies each record in the relation, and all other attributes are dependent on the primary key.

To summarize:

- 3NF ensures that each non-key attribute is determined by the primary key
- This means that the primary key uniquely identifies each record in the relation
- All other attributes are dependent on the primary key.
