Quizplus · Accepted Answer

A foreign key is a column or a set of columns in a table that is used to establish a link with the primary key of another table. This relationship is called a referential integrity constraint, and it ensures that data in the child table (the one with the foreign key) references only data that exists in the parent table (the one with the primary key).
