This tutorial covers a topic in Drupal 7 which may or may not be the version you're using. We're keeping this tutorial online as a courtesy to users of Drupal 7, but we consider it archived.
In this lesson Joe will explain what an entity is and provide a little bit of history about how they came into being. We’ll also learn about some of the differences between custom entities and nodes (which happen to be a type of entity) and when, and why you might want to choose to write your own custom entities instead of using the node system or a more traditional datastore.
