References Between Entities

  • Michael Romer


Entities usually are part of a bigger, interconnected object graph. They have references to other entities. A User holds references to its Posts, while a Post references a Category which references back to the User, who (in turn) sets up the Category, and so forth. As we will see, there are many different ways to establish connections between entities. Connections are characterized by the number of items they connect and the association’s direction. Let’s take a look!
