title: When using an ORM, how to safely send loaded entities across the tiers
body: <p>When a system has N tiers, and when using an ORM, how do you send loaded entities across the tiers ?</p>
  
  <p>Do you use DTO ?</p>
  
  <p>When DTO are not used and the entities are directly sent, how do you protect againt the uninitialized lazy loaded relationship errors ?</p>
  
  <p>Note : this is not a "should N tiers be used ?" question. I assume that the system already has N tiers.</p>
