<h1>Possible Usecases</h1>
<p>There are many use cases for external callbacks,
including:</p>
<ul>
<li value="1">Cascaded deletes, updates.</li>
<li value="2">Referential integrity checks.</li>
<li value="3">Gathering statistics.</li>
<li value="4">Auto assigned fields .</li>
<li value="5">Assigning customary unique IDs for external referencing.</li>
<li value="6">Delayed deletion (objects are marked for deletion when
delete(object) is called and cleaned out of database in a later maintenance
operation).</li>
<li value="7">Ensuring object fields uniqueness within the same class
etc. </li>
</ul>More Reading:<ul><li value="1"><p><a href="possible_usecases/referential_integrity.htm">Referential Integrity</a></p></li><li value="2"><p><a href="possible_usecases/autoincrement.htm">Autoincrement</a></p></li></ul><script type="text/javascript" src="../../SkinSupport/MadCapBodyEnd.js"></script></body>
