<h1>Possible Usecases</h1><p>There are many usecases for external callbacks,
including:</p>
<ul><li>cascaded deletes, updates</li><li>referential integrity checks</li><li>gathering statistics</li><li>autoassigned fields<br></li><li>assigning customary unique IDs for external referencing</li><li>delayed deletion (objects are marked for deletion when
delete(object) is called and cleaned out of database in a later maintenance
operation)</li><li>ensuring object fields uniqueness within the same class
etc. </li></ul>
