Foreign Key References
A foreign key specifies that the values in a column (or a group of columns) must match the values appearing in some row of another table. The Foreign Key References tab allows you to manage foreign keys that being created in other tables and reference for columns of the current table.
Table Foreign Key References are managed within the corresponding tab of Table Editor. Unlike triggers or tables, Foreign Key References are actually not database objects. These are only references to foreign keys. They are designed specially for easy foreign keys management.
