Question 4

Common attribute of two tables is called a foreign key.

Answer

False

Reason — A common attribute between two tables is not necessarily called a foreign key. Instead, a non-key attribute, whose values are derived from the primary key of some other table, is known as foreign key in its current table. A foreign key is used to represent the relationship between two tables.
