What is MVC architecture?

Model View Controller is a well-known software design pattern that may be applied to various frameworks and programming languages, including Python, Ruby, PHP, JavaScript, and others. It is widely used to create web and mobile applications.
MVC is a component of the architecture and its patterns are designed to handle different aspects of an application in development. These design pattern serves to separate the presentation layer from the business logic.

Let‘s see why do developers care about MVC?
It is popular in the app and web development, and it’s one of the most used software design patterns for app and web development.

The Model View Controller design pattern can be categorized into one of 3 buckets;
Model: stores & manages data.
View: Graphical User Interface
Controller: Brains of the application.

The controller collects input from the view, uses logic to translate the input to a demand for the model, the model grabs the data, and the controller passes data from the model back to the view for the user to see in a nice display.

The car driving mechanism can be considered as an example of the MVC model.

Every car consists of three main parts.
View= User interface : (Gear lever, panels, steering wheel, brake, etc.)
Controller- Mechanism (Engine)
Model- Storage (Petrol or Diesel tank)
Car runs from the engine take fuel from storage, but it runs only using mentioned user interface devices.

Advantages of MVC,

  • MVC benefits, are commonly utilized for graphical user interfaces (GUIs)
  • Frequently used in web applications
  • Client and server responsibilities are separated in MVC, which is suitable for web application design.
  • When it comes to development, MVC is a valuable design pattern.
  • Separation of Concerns: code is divided into three buckets based on its function: model, view, and controller.
  • It’s compatible with Ruby on Rails.
  • Loosely Coupled.
  • Unnecessary dependencies are removed.
  • Reusable without any changes.
  • Model classes are reused without modification thanks to MVC.
  • Reuse of code.
  • Adaptable code.
  • Cohesion is high.
  • Simpler to maintain or change.
  • Each component can be evaluated separately (Model, view, controller).
  • Supports Multiple perspectives.

Disadvantages of MVC,

  • It can be difficult to read, adapt to unit tests, and reuse these models at times.
  • Multiple programmers are required to run parallel programming.
  • Multiple technologies must be understood.
  • Because there are so many codes in the controller, maintenance is challenging.

Conclusion:

The MVC architectural pattern splits an application into Models, each of which contains all of the data and logic associated with it.
The user sees the data through the view.
A controller is a component that connects the Model and View components and manages user interactions.
Trygve Reenskaug initially discussed MVC architecture in 1979.
It’s a framework that’s easy to test, extend, and plugin.
Rails, Zend Framework, CodeIgniter, Laravel, and Fuel PHP are some well-known MVC frameworks.
