Foreign Key: In databases, a foreign key is a column or set of columns in a relational database table that provides a link between data in two tables. It refers to the primary key of another table, establishing a relationship between the two tables and enforcing referential integrity. The foreign key identifies a column or a set of columns in one (referencing) table that matches the primary key or a unique key in another (referenced) table. The relationship between the two keys ensures that the data in the two tables remains consistent.
