CRUD with Ember (+ Data)

Ember's official documentation describes a number of low-level APIs, but doesn't offer advice on how to put them together. As a result, a simple task such as creating a simple CRUD application is not obvious to a newcomer.

To help solving this problem, I decided to figure out and document a clear convention for simple CRUD apps, using Ember and Ember Data with no third-party add-ons.
