Correct Answer:
- A primary key is a field that uniquely identifies each record. It's very important that no two records are ever assigned the same value for this unique field.
- It's usually best to have Access create the primary key . If the ID field's data type is AutoNumber, Access automatically assigns a unique value to each record, beginning with 1 for the first record.
- As an alternative, you can select your own primary ke y. For example, you could use each contact's Social Security number as the primary key.
You should use the _____ data type for fields that contain variable length data, such as comments, notes, and reviews.
