represents a logical chunk of UI, responsible for the contents of a single
DOM element.

+
+ Comparing the overall structure of Backbone to a server-side MVC framework
+ like Rails, the pieces line up like so:
+
+
+
+ -
+ Backbone.Model – Like a Rails model minus the class
+ methods. Wraps a row of data in business logic.
+
+ -
+ Backbone.Collection – A group of models on the client-side,
+ with sorting/filtering/aggregation logic.
+
+ -
+ Backbone.Controller – Rails routes.rb + Rails controller
+ actions. Maps URLs to functions.
+
+ -
+ Backbone.View – A logical, re-usable piece of UI. Often,
+ but not always, associated with a model.
+
+ -
+ Client-side Templates – Rails .html.erb views,
+ rendering a chunk of HTML.
