The Model-View-Controller (MVC) framework is an architectural/design pattern that separates an application into three main logical components Model, View, and Controller. Each architectural component is built to handle specific development aspects of an application. The model is responsible for managing the data of the application. It represents the state of the application and communicates with the database to perform operations on the data, such as creating, reading, updating, and deleting records. The model is independent of the user interface (UI) of the application and can be used by multiple views.

The view is responsible for generating the UI of the application and displaying the data to the user. It receives data from the model and presents it in a user-friendly format, such as a table or a chart. The view is also responsible for capturing user input and sending it to the controller.

The controller is the middleman between the model and the view. It receives requests from the user, such as clicking a button or submitting a form, and sends them to the appropriate model or view. The controller also coordinates the model and the view, ensuring that the correct data is displayed to the user.

One of the main benefits of the MVC architecture is that it allows developers to make changes to the application without affecting the other components. For example, if you want to change the UI of the application, you can modify the view without affecting the model or the controller. This makes it easier to maintain and update the application over time.

Another benefit of MVC is that it encourages the development of reusable code. Since the model, the view, and the controller are independent of each other, you can reuse the same model or view in multiple applications. This saves time and effort and allows developers to focus on building new features instead of reinventing the wheel.

MVC is not the only software design pattern, but it is widely used in web development and has been adopted by many popular frameworks. These frameworks provide a pre-defined structure and set of tools that make it easier to implement the MVC pattern in your projects.

However, using a framework is not necessary to implement MVC. You can also design and build your own MVC application from scratch using your preferred programming language and tools. This gives you more control and flexibility, but it also requires more effort and expertise.
