Definition
A foreign key establishes a connection between two tables, with table T1 referring to the primary key of table T2. In T1 foreign key fields are created, to which the primary key fields of T2 are assigned.
The table to be checked (T1) is termed the foreign key table, whilst table T2 is termed the check table.
