Model View Controller 101: Why your web project may need MVC

Why Your Web Project may need MVC 

Software development has advanced a lot in recent times. Nowadays, the agile approach has replaced the waterfall approach, and computer applications are running a lot smoother. 

One of the major changes in software development includes the introduction of the Model View Controller to develop web applications.

What is Model-View-Controller?

Model View Controller refers to a software design pattern used for user interface development which categorizes program logic into three interconnected parts; the model, the view and the controller. 

These interconnected parts handle unique development features of a web project and application. The three interconnected parts of an MVC-model include;

Model

This is the part that represents both the user and the data. The model defines where the user’s data is stored. Since the model does not regulate the views and controllers of any project, in the event that changes might be made, it notifies the user. 

Views

A view is the visual portion of the MVC-model. Views display the data in any web application using the model class object. This part is used to create interfaces that show the actual result to the users. Views act as the link between the users and the controller. 

It is the views that get requests and commands from the user and, in return, inform the controller level. Their folders are always contained in view files located in the project. The model’s controller usually has one or more action methods and can provide one or more views for the developer. 

Controller

In simple terms, the controller is the brain of the entire system. The controller regulates the interaction between the users and the MVC-system. 

Controllers are also the regulators of all application executions of the system. The controller is able to determine all users’ output and send them messages that also go through the views.

Popular Web Development Frameworks that Apply MVC-Concept

There are various web development frameworks that get some of their concepts from Model-View-Controller. They include;

Django

Although it handles its own controller functions, Django has some concepts attributed to Model-View-Controller. It eradicates the approach of having code in one file. Through it, code can be stored in different files. 

Laravel

In this framework, the model provides the user interface that is most suitable for the user. The controller receives any requests or commands made by the user and the model, and the view are complete the appropriate actions as required. We typically incorporate this framework with another front end framework to help decouple the front and back end.

Zend

Like the model, the Zend framework incorporates the same levels, namely, model, controller, and views in order to identify requests from users and offer appropriate feedback in terms of messages.

Angular

This framework has variables texts that go through a set that emulates the controller and replaces them variables that the user requests. This controller is responsible for regulating the relationship between the model and the view, which in Angular framework is represented by HTML.

Ruby on Rails (Ruby)

This framework uses the same design as the model, with folders named as controllers and models and views. However, the folder named views in this framework has HTML files stored in them and the models, and views contain ruby files.

The Purpose of Model-View-Controller in Website Development

1. Faster development process

It is used to simplify and reduce development time. This is because it has three different parts, which gives room for more than one programmer to work on a particular part. One programmer can handle the views; another can tackle the controller while the other can work on the overall model. 

This helps create more business logic for the whole website development project. This way, website development is completed three times faster and more efficiently than if other patterns were used.

2. SEO friendly results

If you want to ensure that the web project you’re developing will be more search engine optimized, then it is the perfect fit for you. It ensures that your web page URLs can easily appear at the top of all search engine results if the internet user searches for a similar topic. 

This is very important for your website as you could end up getting more traffic and, in return, even more interactions and awareness for your brand.

3. Better editing

Sometimes when you’re editing your web project, you want a particular section updated.

Model-View-Controller ensures that you can make changes to the font used, the color, and layouts without tampering with the whole project. This is very helpful as it makes editing work a lot easier.

4. To generate multiple views 

With Model-View-Controller, you can always generate more multiple views for your model ensuring that your applications can be accessed in different ways. Also, it minimizes any chances of code duplication. 

Conclusion

Adopting this model for website development has proven to be cheaper and time-effective for most organizations. It also ensures that these organizations can meet all the clients’ needs when designing website applications and develop lasting relationships with them.
