Quizplus · Accepted Answer

A foreign key is a column or a set of columns in a table that is used to establish a link between the data in that table and the data in another table. It is called a foreign key because it originates from a foreign table and references the primary key of another table. When a foreign key is used in a table, it is required to match the primary key of another table to maintain referential integrity.
