Model

 Objects that are used to interact with the data that is stored in the database. Most of the logic goes into the model.​

View

What the user interacts with. Consists of the HTML, CSS, and javascript to display the data.

Controller

The connection between the models and the views. It usually takes the model’s data and populates the views with it.

MVC
