The Model-View-Controller (MVC) framework is a software design pattern commonly used in web development to separate an application into three interconnected components: Model, View, and Controller. The Model represents the application’s data and business logic, the View displays the user interface, and the Controller handles user input and updates the Model or View accordingly. This separation promotes organized code, easier maintenance, and scalability. By isolating different parts of an application, MVC enhances modularity, allows for parallel development, and simplifies testing. Popular frameworks like Django, Ruby on Rails, and ASP.NET MVC implement this architecture to streamline development processes.
