MVC (Model-View-Controller) is a software architectural pattern commonly used in web development to organize and structure the codebase. It provides a structured way to separate the application logic into three interconnected components:
- Model: The Model represents the data and business logic of the application. It manages the data, performs data validation, and implements data access and manipulation logic.
- View: The View is responsible for the presentation layer of the application. It defines how the data should be presented to the user. In web development, the View is typically implemented using HTML, CSS, and JavaScript.
- Controller: The Controller acts as an intermediary between the Model and the View. It receives user input from the View, updates the Model accordingly, and notifies the View to update its presentation. It encapsulates the application's logic and orchestrates the interactions between the Model and the View.
The separation of concerns provided by MVC allows developers to work on different components independently, which improves code maintainability and reusability. It also promotes a clear separation of user interface (View) from the underlying data and business logic (Model and Controller).
