There are four questions given, and each question has four options (a total of 16 options). The mark of each option is six. So, you will answer for 16*6=96 marks. If you get 96 out of 96, you will be awarded 4 marks. So, the total mark is 100. 1. Assume there is a table1 (a1, a2, a3, a4). In this table, either a1 or a2 can uniquely identify the table rows. a. True/False: {a1, a2} is a Candidate key. b. Choose a Primary Key for the table. Motivate your choice by making proper assumptions. c. List all Candidate Keys for the table. d. List at least four possible Superkeys for the table. 2. Assume there is a table2 (61, 62, 63, b4). In this table, b1 and b2 combinedly can uniquely identify the table rows. a. True/False: {b1, b2, b3} is a Candidate key. b. Choose a Primary key for the table. Motivate your choice by making proper assumptions. c. List all Candidate Keys for the table. d. List at least three possible Superkeys for the tableStep by Step Solution
