Question

State True or False:

If table A has 6 rows and 3 columns, and table B has 5 rows and 2 columns, the Cartesian product of A and B will have 30 rows and 5 columns.

Answer 1

This statement is true.

Explanation:
In a Cartesian product of two tables A and B:

Degree of resultant = Degree A + Degree B

= 3 + 2

= 5

Cardinality of resultant = Cardinality A × Cardinality B

= 6 × 5

= 30

Hence, the statement is correct.
