Hi - I'm completely new to Drupal, *wave*.

I have an external system with a few million entities accessible via web services.

Ideally what I would like to do is create a module that makes those entities appear in Drupal as Nodes, but not really be Nodes in the sense of being in the Drupal database.

I would like to be able to view/manage these entities through the Drupal UI as if they were bona-fide nodes.

Is this even possible?

Thanks.
James.
