Examine the following table:

What is the degree of this table?

A.
20

B.
25

C.
5

D.
4

Explanation:
The question being asked is the degree of the displayed table. The degree of a table refers to the
number of columns that a table has. The number of columns contained in a table is referred to by
the term degree of the table; if the degree of a table is increased by 1, it means that a new column is
added to the table. The degree of the table denotes the number of columns or attributes. Since the
table displayed has four attributes, the degree of this table is four (4).
Answer C, A, and B are incorrect. These are not the appropriate values for the degree of the table
displayed.
