What is the MVC framework?

MVC stands for model, view, and controller. It defines the entire architecture of the web applications. We can make manageable apps through MVC. As it is divided into three parts, each part plays a vital role in developing and maintaining the applications. In this Answer, we will discuss the features, advantages, and disadvantages of MVC.

Model

The model is the place where all the data of the application is stored. Suppose a user wants to update or retrieve the data. The controller will first request the model, and then the model will return the data after communicating with the database. It is also responsible for catering to the controller's requests and views.

View

Simply saying, a view is the application's front-end in MVC; after receiving the raw data from the model, it converts it into an attractive, readable format. It can directly request the model to retrieve the data. It is also used to plot the graph and charts as well. Views are used to represent the output to the user.

Controller

To process all the incoming from the user, we use the controller. It acts as the bridge between the model and the view. For example, the blog controller will retrieve the data from the blog model. It will update it as per requirements or send it to the blog view to display the blogs to the controller.

Example

Consider an example in which we have a client, a server, and a database. Our clients want to retrieve the data that is stored in the database. Let us say that data is the list of blogs. The client's request will be passed to the controller, who then passes the request to the model. As the model has access to the database, it will communicate with it and return the data to the controller. As the data returned by the model is in a raw format to make it interactive, we pass the request with the data to the view. At this stage, the view is responsible for proper formatting and will show the data to the client.

  • Ruby on rails

  • Laravel

  • React

  • Express

  • Angular

  • Django

  • Spring

Conclusion

MVC is an architecture that provides feasibility to its user to make manageable web applications. It provides various features such as reusability and cleanliness of code. It is easy to understand the code of the applications that are built with the help of MVC architecture because everything is defined in the best way. However, it solves many complex problems related to web application development, but there are also limitations. The limitations of MVC are covered by another framework which is MVVM (model-view-view-model). The choice of architecture to make websites depends upon the application's requirements.
