• MVC

Model

• This is where we store the data that underlies the solution or application that we are building.
• Holds the domain logic and business objects that interact with the database.

Controller

• Controllers are unique in the sense that they seat in between models and views
• In conjunction with the router, they handle the internal navigation of your rails app.

HTTP and the web

• Request and Response
• HTTP is stateless
• REST - Set of commands that can modify state by visiting a particular URL
• Resource - The state/thing that is modified by CRUD

View

• Handles presentation of content to user
• Most user interaction happens here
