Question 1: S is a relation instance. If S has 6 tuples in it, then how many tuples are there in the result of the following SQL query? SELECT * FROM S S1, S S2;36 = 6 * 6
Question 2: Let R(A,B,C,D) be a relation, where (A, B, C) is the Primary Key of R, and attribute D cannot be NULL. Assume A’s domain has 5 different values, B’s domain has 2 , and C has 4, and D has 3. What is the maximum number of tuples that can be in an instance of R? 40 = 5 * 2 * 4 (Primary Key is unique)
Question 4:
