Answer:

You can enter data based on the defined data type.

A primary key uniquely identifies a record.

Explanation:

In a database, you can only enter data that matches the data type you have specified for that field. Therefore, you can enter text in fields with the text data type; numbers in fields with the number data type; or images in fields with the BLOb data type. You can have fields where data entry is optional. A primary key eliminates the chance of duplicate entries of the same record in a table.
