 *         In the database, a link between <b>two fields</b> is declared by a (soft or hard) foreign key.
 *                 <ul>
 *                      <li>The field declared as a foreign key belongs to the "dependent" table.</li>
 *                      <li>The other field belongs to the "reference" table.</li>
 *         </ul>
 *     </li>
