MVC architecture structure in Ruby on Rails

What is MVC

MVC is a design pattern and was developed in 1979 by Trygve Reenskaug. MVC dictates that the system be split into three distinct parts, a Model, View and Controller. This approach organizes the code into separate components, thereby facilitating maintainability.

Model

The Model generally contains the data for the application and is usually linked to a database back-end. This is the data structure that the application uses.
It contains the application state and also most of the business logic. The model has no knowledge of the user interfaces.

View

The view refers to the interface that is presented to the end-user. The view does not do any processing, but simply acts as the presentation layer, displaying the application data.

Controller

The controller receives events from the outside world [ or through some view] and performs some processing

It interacts with the model and redirects to the appropriate view.
