What does the architectural pattern MVC mean to you?

MVC stands for Model-View-Controller and is an architectural pattern that divides an application into three interconnected parts.

• Model: Represents data and business logic. Responsible for storing and managing data.

  // Example of a model in Rails
  class Product < ApplicationRecord
    validates :name, presence: true
    // ... other logic
  end
  

• View: Responsible for displaying data to the user. This is the presentation layer.

  <!-- Example of a view template in Rails -->
  <h1><%= @product.name %></h1>
  <p><%= @product.description %></p>
  

• Controller: Acts as an intermediary between Model and View. Handles user input, updates the Model, and selects the View for display.

  // Example of a controller in Rails
  class ProductsController < ApplicationController
    def show
      @product = Product.find(params[:id])
    end
    // ... other actions
  end
  

MVC promotes separation of concerns, facilitates the development of large applications, improves testability, and code reusability. It is often used in frameworks such as Ruby on Rails.
