'Any relation in bcnf' is in '3nf' but the 'converse is not true' is a True statement.
Explanation:
- The database table is said to be in '3NF' only if that 'table' is in the 'second normal form (2NF)' and all the 'attributes' in the 'table' that does not belong to the candidate key will depend directly on each candidate key in that table.
- The 'database' table is in 'Boyce-Codd' Normal Form '(BCNF)' only if there is no 'non-trivial functional attribute' dependency on anything other than a candidate key superset. BCNF is occasionally mentioned to as '3.5NF', or '3.5 Normal Form'.
