Answer 1

Answer #1

Solution:

The candidate key is the key that is used to identify the other fields in the table.

It must be minimal.

The process of obtaining the candidate key is as shown below.

A able to identify all the candidate key must be in the table. other attributes option a) AE once. the values for In 55 it oc

Option d) CD С E 5 S 5 л 5 4 CD is not candidate key Optron el All of above of the above. option fx none option of is corect
