Hello everyone, my name is Hemant, and in this blog, I will explain the most important part of development: MVC.

Overview

MVC stands for Model-View-Controller. It is a widely used software architectural design pattern that organizes our code efficiently. It separates our code functionality and logic. Almost every language and framework utilizes MVC or some part of it, making it one of the most frequently used design patterns in development. This organization promotes structured programming and enhances the overall development process.

Why do we need MVC?

Before diving into details let's understand why we need it.
What if there were a design pattern, a paradigm, or software architecture that structures our code in a way to:

1. Made it easier to maintain, separate code

2. Made it easier to read through what was already coded

3. And allow developers to collaborate, and work on a specific part of the app and not be afraid to make changes

Now, let's dive into the three components of MVC: the Model, View, and Controller.

Model:

First, we have the Model. The Model refers to the data and business logic, acting as the brain of the web application. All data-related logic is handled by the Model, directly interacting with databases and having a schema that serves as the database blueprint. It also manages queries like select, insert, update, and delete in frameworks that support multiple databases.

View

Moving on to the View, takes care of the user interface of the application, providing users with what they see when interacting with the app. Typically comprising HTML and CSS, the View receives dynamic data from the Controller. The template engine enables the use of dynamic data, allowing for the incorporation of variables and logic into the HTML output.

Controller

Lastly, the Controller serves as a middleware between the Model and View, handling user inputs such as visiting pages, clicking links, and submitting forms. It interacts with the Model to retrieve data and then passes it to the View for display. The template engine processes variables and logic before generating the HTML output.

So here is an example diagram: The user sees the view in the browser and interacts with it to send a request to the router (by clicking a button or submitting a form). The router then manages that request to the controller based on the route. The controller checks if the request requires data, then interacts with the model. The model communicates with the database to retrieve the data. After obtaining the data, the controller manages that data to the view. The template engine processes its logic and generates the HTML, sending it back to the user. This is how the MVC works.

Conclusion

In summary, the MVC architecture ensures a structured and efficient development process, enhancing collaboration among developers and improving the overall user experience of web applications.
