The MVC (Model-View-Controller) is most important a software architectural pattern commonly used for developing user interfaces and applications.

If you are a back-end or full-stack software engineer, you really need to understand this pattern. It is quite easy to understand and apply to your app, let's dive in!

MVC architectural

I. Model:

This represents the data and the business logic of the application. It is responsible for managing the data, including retrieving, storing, and processing it. The model notifies the view of any changes to the data.

II. View:

The view is responsible for displaying the data to the user and sending user commands to the controller. It presents the information in a way that is easy to understand and interact with.

III. Controller:

The controller acts as an intermediary between the model and the view. It receives user input from the view, processes it (often interacting with the model), and returns the results to the view to be displayed.

Benefits of MVC:

  1. Separation of Concerns: Each component has its own responsibilities, making it easier to manage and maintain the code.

  2. Testability: Since the business logic is separated from the user interface, it is easier to test and debug each part independently.

  3. Scalability: New features can be added with minimal impact on existing components.
