[Year 12 IT Apps] Another Questions: VITTA Practice Exam 2 Question 56

[Geoff Moss]

Hi Jo

15-ALL

While not having seen the Practice Exams, and using the information you provide, your reasoning is IMHO correct.  The primary key defines a quality on the data type, in that the data in that field must be unique for each record.

On its own the primary key cannot be a data type.

Hope this helps
