Expert Solution

Step 1

Introduction

Understanding the different kinds of keys in a database can be a bit confusing. To start, let's define each term:

Super Key: A super key is any combination of attributes that uniquely identifies a tuple in a relation. There may be one or more attributes in it.
Candidate Key: A candidate key is a subset of the super key attributes that can uniquely identify a tuple. There may be one or more attributes in it.
Primary Key: A primary key is one of the candidate keys that is chosen to uniquely identify a tuple in a relation. It must consist of one attribute.
