What is MVC framework?

Model View Controller or MVC is a software architectural pattern for implementing user interfaces on computers. It is an architectural pattern that separates an application into three main logical components: the model, the view, and the controller. The MVC design pattern decouples these major components allowing for efficient code reuse and parallel development. Each of these components are built to handle specific development aspects of an application. MVC is one of the most frequently used industry-standard web development framework to create scalable and extensible projects.

As with other software architectures, MVC expresses the "core of the solution" to a problem while allowing it to be adapted for each system. Following are the components of MVC -


The Model component corresponds to all the data-related logic that the user works with. A model stores data that is retrieved according to commands from the controller and displayed in the view.


The View component is used for all the UI logic of the application. It generates new output to the user based on changes in the model.


Controller represents the classes connecting the model and the view, and is used to communicate between classes in the model and view. It process all the business logic and incoming requests, manipulate data using the Model component and interact with the Views to render the final output.
