Today’s article is about MVC design pattern. I won’t only cover the theoretical aspect that you probably already know. My discussion is full of real-world examples.

What is MVC?

MVC is a software architectural pattern commonly used by web developers to improve the organization of their applications, specifically their code. It stands for Model–View–Controller. The MVC pattern mainly relies on separating the application into three interconnected parts to simplify the flow of the application.

Model:

It represents the data and business logic of the application. It is responsible for storing, manipulating, and retrieving data. I know it all sounds like Greek to you! So let’s take some examples. The MVC pattern doesn’t store anything! It just holds the code that performs the following jobs: sets the rules for managing data, saves any new data upon Controllers’ request, deletes data upon Controllers’ request, and updates data upon Controllers’ request.

View:

It represents the user interface of the application. It is responsible for displaying data to the user and receiving input from the user. In other words, the View is where you interact with the application. For example, the WhatsApp contacts list is considered a View for the WhatsApp application. It’s where you can see your contacts and take actions like calling a friend. In a few words, the place where you are reading this article is also a View.

Controller:

It acts as a bridge between the Model and View. It is responsible for receiving data from the View, doing some processing, delivering it to the Model (if needed) to perform some manipulation over data like saving, deleting, or updating using the code that is in the Model. Think of the Controllers like a waiter in a hotel. They connect the guest with the different parts of the hotel.

In conclusion, the main advantage of using the MVC pattern is that it promotes separation of concerns, making the code more modular and easier to maintain. It also enables multiple developers to work on different components of the application simultaneously without interfering with each other’s work. All in all, it makes the development process more enjoyable!
