Which normal form ensures that there are no repeating groups of data and all non-key attributes are fully functionally dependent on the primary key?OptionsFirst Normal Form (1NF)Third Normal Form (3NF)Boyce-Codd Normal Form (BCNF)Second Normal Form (2NF)
Solution
To ensure that there are no repeating groups of data and all non-key attributes are fully functionally dependent on the primary key, we need to choose the appropriate normal form.
The normal form that satisfies these requirements is the Boyce-Codd Normal Form (BCNF). BCNF is a higher level of normalization compared to First Normal Form (1NF) and Second Normal Form (2NF).
In BCNF, every non-trivial functional dependency in the relation is a dependency on a candidate key. This means that all attributes in the relation are functionally dependent on the primary key, and there are no partial dependencies or repeating groups of data.
Therefore, the correct answer is Boyce-Codd Normal Form (BCNF).
