Question

Quizplus · Accepted Answer

Second Normal Form (2NF) requires that the table is in First Normal Form (1NF) and that all non-key attributes are fully functional and dependent on the primary key. However, the correct definition of 2NF does not specifically state that the table identifier should not be a composite key. My previous response was incorrect as 2NF actually allows for composite primary keys but requires that all non-key attributes must be fully functionally dependent on the entire primary key. Therefore, none of the provided options accurately describe 2NF.
