Question 8In the following student table, which attribute could be used as a primary key?Student first nameStudent last nameMobile numberCarl Merlo07445532123MarkNero074565323271 pointStudent last nameMobile numberStudent first name
Solution
The attribute that could be used as a primary key in the student table is the "Mobile number". This is because a primary key is a unique identifier for each record in a database. In this case, the mobile number is likely to be unique for each student, making it a suitable choice for a primary key. The student's first and last names are not suitable as primary keys because there could be more than one student with the same name.
