Question

Somya has made a database table in Access containing fields like Student_name, Class, Roll_no and contact_no. She has set the primary key for the field 'Student_name'. Has she done the right thing by setting the primary key for this field?

Answer 1

Answer:

No, she could have set the Roll_No as the Primary Key because in many cases, some children have the same name andsurname. But, roll no is different for each student. So, setting the Roll_no as Primary Key was better and much more ideal...
