Final answer:
To be in the third normal form (3NF), a table must meet certain conditions, including: each non-key column must depend only on the primary key, the non-key columns must not contain repeating values, and each non-key column must depend on the entire primary key is incorrect.
Step-by-step explanation:
In order to be in the third normal form (3NF), a table must meet certain conditions. One of the conditions is that each non-key column must depend only on the primary key. This means that the values in the non-key columns are determined by the primary key and not by any other non-key columns. This helps to avoid data redundancy and ensure data integrity.
Another condition for 3NF is that the non-key columns must not contain repeating values. Each value in the non-key columns should be unique, and there should be no repetition of values. This also helps to eliminate redundancies and inconsistencies in the data.
The statement each non-key column must depend on the entire primary key is incorrect. The non-key columns can depend on a portion of the primary key, as long as they are not dependent on any other non-key columns. This condition is not necessary for 3NF.
