Model

Model is used to access data from the database. If we need to get data from the database so we have to create a query (logic) for the database.

View

The view is used to create a view of the website. We can say, design of the website. We can create view (HTML, CSS, JavaScript, Ajax etc.). Users directly interact with the view of the website.

Controller

A controller is responsible for controlling the way that users interact with the MVC application. A controller is used to create logic for an application.
