This document discusses the model-view-controller (MVC) framework in Ruby on Rails. It shows a User model class that has_many books and sets its table name and primary key. Diagrams illustrate how the controller receives requests from the URL and params, interacts with the model to find or save data, and sends responses back to the view to display to the user. The MVC pattern separates an application into these major components to organize code and responsibilities.
