MVC – Why it is better?
MVC is an acronym for Model, View, and Controller. It’s a product development architecture. The traditional approach of programming works on Input -> Process -> Output approach while MVC works on Controller → Model -> View.
During, the traditional approach of programming, the UI coding, business logic, and application data domain was written into a single file which creates a lack of maintainability, testability as well as scalability of the application.
With the emerge of MVC approach, it helps you create applications that separate the different aspects of the application (input logic, business logic, and UI logic), while providing a loose coupling between these elements. The pattern specifies where each kind of logic should be located in the application. The UI logic belongs in the view. Input logic belongs in the controller. Business logic belongs in the model. This separation helps you manage complexity when you build an application because it enables you to focus on one aspect of the implementation at a time. For example, you can focus on the view without depending on the business logic.
The MVC model or “pattern” is commonly used for developing modern user interfaces. It provides the fundamental pieces for designing programs for desktop or mobile, as well as web applications. It works well with object-oriented programming since the different models, views, and controllers can be treated as objects and reused within an application.
Below is a description of each aspect of MVC:
1. Model
A model is data used by a program. This may be a database, file, or a simple object, such as an icon or a character in a video game.
2. View
A view is the means of displaying objects within an application. Examples include displaying a window or buttons or text within a window. It includes anything that the user can see.
3. Controller
A controller updates both models and views. It accepts input and performs the corresponding update. For example, a controller can update a model by changing the attributes of a character in a video game. It may modify the view by displaying the updated character in the game.
IMPORTANT BENEFITS OF MVC MODEL
1. Accelerated Development Process:
How can you increase the development speed by adopting MVC architecture? Whenever an MVC architecture is being employed in developing a web application, one developer can concentrate on the view component whereas the other can focus on controller and create business logic. Therefore, when compared to other development models, the MVC model results in higher development speeds i.e. up to three times.
2. Develop Multiple View Components for your Model:
The MVC architecture empowers you to develop different view components for your model component. As you can witness an ever-increasing demand for new ways to access your web apps, MVC architecture is your one-stop solution for developing different view components. Also, the MVC model limits code duplication and separates the business logic and the data from the display.
3. Supports Asynchronous Method Invocation (AMI):
Undoubtedly, MVC architecture works cohesively well with JavaScript Frameworks. As a result, you can run MVC apps on desktop widgets, site-specific browsers, and PDF files. The MVC architecture supports asynchronous method invocation (AMI) that bolsters developers in building quick loading web apps.
4. Modifications do not Affect the Entire Model:
Your web app’s UI gets new updates every now and then than your actual business model/rules. These include optimizing the color, layouts, font family, font size, and additional support for mobile/tablets. As already said, since the model, view and controller are independent components, making changes in the MVC architecture is very easy. Moreover, making changes in the model component will not have any adverse effects on the architecture.
5. MVC Model Returns the Data Without Formatting:
You can use and call the same components and put them into use with many interfaces. For instance, you can format data with HTML.
6. Ideal for Developing Large Size Web Application:
MVC architecture works exceptionally well when your web app demands the support of a huge developer team, and for web designers who require complete control over the app’s behavior.
Therefore, MVC architecture is a one-of-a-kind approach to building web apps. As the MVC frameworks come packed with the above-mentioned advantages, it is easy to implement in your framework. The adoption of MVC architecture results in the lesser expense of time & money, and the ability to create multiple views makes it the best architecture for web app development.
