What is MVC? And the Advantages and Disadvantages of it
Sat, 08 May 2021
MVC- “Model-View-Controller.” MVC is a model of application design consisting of three interconnected parts. These include the model-data, the view-user interface, and the input controller-processes.
Commonly, the MVC model or template is used to design modern user interfaces. It offers basic components for developing desktop or mobile apps, and also for web applications. This fits well with object-oriented programming because within an application the various templates, views, and controllers can be viewed as objects and reused.
The definition below for each element of MVC is:
Model
A model is a data that a system uses. It can be a database, file, or basic object in a video game, such as an icon or character.
View
A view is the way objects are viewed within an application. Examples involve a window or buttons or text displayed inside a window. It covers everything the user might see.
Controller
The controller is the heart of MVC. A controller updates both models and views. It accepts input and performs the corresponding update.
The view displays the model for the user. The controller accepts user input and updates the model and views accordingly. While MVC is not required in application design, many programming languages and IDEs support the MVC architecture, making it a common choice for developers.
Working of MVC:
In MVC, when a user sends the request from the Web Browser, the controller first comes up. It is sent to the right View by the controller. The request for data is from the user, and the controller goes to the model class since, as already described, the model always carries data. If we change one layer that not impact other layers. It is a significant advantage which makes MVC great.
Advantages and disadvantages of MVC:
Advantages of MVC
The development of the application becomes so fast
It is easy for multiple developers to collaborate and work together
It is easy to update the application
It is easy to Debug as we have multiple levels properly written in the application
Disadvantages of MVC
It is difficult to understand the MVC architecture
It must have strict rules on methods
The drawbacks of the MVC component are not many. And the drawbacks are not that big, so they are very easy to ignore as compared to all the benefits we receive.
Conclusion:
To remove the model-view dependencies, the MVC design pattern adds a controller class between the view and the model. The layout, and probably the view, can be made reusable without alteration, with the dependencies removed. The customers easily get reliable apps, the company saves money and the developers don’t go foolish.
