A table is in BCNF if every determinant in that table is a candidate key. If a table contains only one candidate key, 3NF and BCNF are equivalent.
A table is in Boyce-Codd normal form (BCNF) if every determinant in the table is a candidate key.
A determinant is any attribute whose value determines other values with a row.
If a table contains only one candidate key, the 3NF and the BCNF are equivalent.
BCNF is a special case of 3NF.
