Model-View-Controller (MVC) is a software design pattern commonly used in web development. It divides the application into three interconnected components: the model, the view, and the controller.
Model: This component represents the data and logic of the application. It encapsulates the business rules, data access, and data manipulation. The model is responsible for managing data, and it notifies the view and controller about changes in the data.
View: The view component handles the user interface (UI) part of the application. It displays the data from the model to the users and allows them to interact with the application. The view is responsible for presenting the data in a visually appealing and user-friendly way.
Controller: The controller acts as the intermediary between the model and view. It receives user input from the view and updates the model accordingly. It also notifies the view about changes in the model, so the UI can be updated. The controller handles user interactions and controls the flow of the application.
The MVC pattern promotes a separation of concerns, making the application easier to develop, test, and maintain. It allows for modularity and reusability as each component has a specific responsibility. MVC is widely used in frameworks like Ruby on Rails, Laravel, and ASP.NET MVC for building scalable and maintainable web applications.
