Ember: What is the accepted paradigm for saving data to the back-end?

I am new to Ember and am used to the MVC model of creating controllers to move data between the view and the server. With Ember, it appears that controllers are support but there is very little documentation on them on the Ember website. From what I can tell, there is an alternative method to save data through the route. Is there an accepted paradigm for how to save data from the front-end to the back-end in Ember?
