This is known as a "foreign key" (the data it points to is foreign to the current record). It is also commonly called a "foreign key constraint", usually in database systems where the database will perform additional data integrity checks when a primary key is updated or removed (such as restricting deletion of the primary record, clearing the value in the foreign key field, or cascading the deletion to the related records).
