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 degreeof 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.
