Which of the following statements accurately describes

Solution

Third Normal Form (3NF) is a level of database normalization that builds on the requirements of First Normal Form (1NF) and Second Normal Form (2NF). A table is considered to be in 3NF if it satisfies the following conditions: • It must be in 2NF: This means that the table must already be in First Normal Form (1NF) and have no partial dependencies, where non-key attributes depend on a portion of a composite primary key. • No Transitive Dependencies: All non-key attributes must be directly dependent on the primary key, not on other non-key attributes. This eliminates transitive dependencies, where a non-key attribute depends on another non-key attribute rather than on the primary key directly. By ensuring that there are no transitive dependencies, 3NF reduces redundancy and improves data integrity by ensuring that data is only stored in one place. This helps prevent anomalies and inconsistencies when updating the database.
