The model contains the data
There is no view because we are going to return serialized JSON
You will see how to consume this in a bit
The controller does all of the work

This data is returned through the controller

9. Routings

And it’s a bit magical

10. MVC Routes (1)
Routes provide the mechanism to map URLs into a corresponding call to a controller function
Roughly speaking, the format of a route is /api/{controller}/{action}/{id}
