Foreign Keys

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. We say this maintains the referential integrity between two related tables.

Foreign Keys are managed on the Foreign Keys tab of the Table Designer. Just simply click/double-click a foreign key field for editing. A right-click displays the popup menu or using the toolbar below, allowing you to create new, edit and delete the selected foreign key field.
