What is MVC? Definition, Benefits & Examples of the Framework

If you are learning how to make a website more effective, of course you are already familiar with the term MVC, right? MVC is a website architecture concept model-view-controller which is famous for its good performance so it is widely used in almost all framework famous even for development mobile app development.

So what the hell excess model-view-controller this? And how does it work? Instead of being curious, let’s immediately see the following explanation!

What is MVC?

MVC is an architectural pattern framework that makes the application divided into 3 main components, namely: model, viewas well as controller. Basically, when a process web development in progress, There are a number of codes and each has its own function.

These codes serve to store data webmake view web looks attractive, and monitors how it works web. Well, the purpose of each component in MVC is to organize every code in the process web development the.

View controller models is a pattern that can be used for many framework with a variety of programming, such as Python, PHP, JavaScript, Nodejs, and others. MVC can also work well for object-oriented programming.

That’s

because every MVC component can be used as an object and reused in applications. Therefore, MVC is one of the standards web development framework most often used to build large-scale site projects.

MVC Components

As mentioned above, there are 3 main components of MVC, and these three components have their respective functions and roles. Here’s the explanation.

  • Model: The first component of MVC is a model that functions to prepare, organize, and even manipulate data in the database.
  • View: serves to present information in the form of Graphical User Interface or GUI for short.
  • Controller: serves to connect and control model as well as view so that they can be connected.

Frameworks Using MVC

Next, there are several framework that have used MVC as their architectural pattern, including:

  • Python frameworks: Django, Turbogears2, Watson-Framework, and so on.
  • PHP Frameworks: Laravel, Symfony, CakePHP, Zend, Codeigniter (version 3 and back is not recommended to learn).
  • Nodejs Frameworks: Express, Adonis, Sails.js, Total.js, Mean.js, Mojito.

Benefits of the MVC Method

Some of the benefits of the MVC method include:

1. A more efficient website development process

The first benefit of the MVC method is that it can create processes web development be faster. This is because MVC separates website into three components. Component model and controller done by team back end developer while the component view done by team front end developer and the UI/UX team.

For example, the UI/UX team has finished designing the web front page design, so the team back end nor front end can start compiling coding programming for the design. Then, the UI/UX Team can continue designing other pages.

If the process of developing a website is divided using the MVC method, it can make it easier web developer to focus more on their respective parts. So, they can more quickly find and find bugs and then deal with them.

For example, when the chat feature on a hotel ticket sales website doesn’t work, the problem may lie with the buttons or data. If it turns out that the problem is found in the button, namely in the viewthen team front end developer can deal with it right away.

3. Easier testing process

The next benefit of the MVC method is to make sure the website runs well by doing testing. MVC can facilitate the testing process for each part of the website. In addition, the documentation process for each website feature can be more effective and neat.

4. The process of maintenance or maintenance is easier

Another benefit of the MVC method is that it makes it easier for developers to use scripts in a neater and orderly manner, so that the maintenance process becomes easier.

For example, you want to add the ‘exchange shop points’ feature on your online store website. With MVC, the team back

end and front end developer it will be easier to find the script code that needs to be added to the feature.

Characteristics of the MVC Concept

Looking at the definition and benefits, some of the characteristics of MVC are:

  • Back to the original sense, MVC is framework programming that divides 3 main components (Model, View, and Controller).
  • MVC is a template that is very easy to test, so it can be developed and implemented in a variety of programming code.
  • MVC will also offer complete control over web development such as HTML and URLs.
  • Features that are owned by JSP, ASP.NET, Django, and others can take advantage of the MVC method.
  • Test Driven Development (TDD) on the website is supported by MVC.

How MVC Works

The next thing you need to know about MVC is the flow or how it works. Here’s the explanation.

  • First, part team view requesting a certain amount of data to be presented to the user in the form of a graphic design.
  • The request is then accepted by the team controller and submitted to the modeling team for further processing.
  • Section team model will research and process the data into the database.
  • After the data is searched and processed, the team model will provide the data to the division team controller to show to the team view.
  • It doesn’t stop there, controller will also control the data processed by the model in the view to be presented to the user.

Advantages of MVC

In addition, there are several advantages that you will get when using the MVC concept in your website development, including:

1. Support asynchronous programming technique

MVC is a multifunctional programming technique, because it can relate to framework JavaScript. In addition, MVC was also created to be able to handle work with PDF files, special web browsers, and computer desktop widgets.

Therefore, the components in MVC can support asynchronous programming techniques which make it easier for developers to develop web faster.

2. Program code changes will not affect the entire web

Another advantage of MVC is that any changes to the program code in the model will not affect the entire web. For example, the UI section (user interface) often change the design, such as changing colors, layouts, fonts, and others. So, with the component viewyou can change the appearance of the UI more easily and organized.

Example of Using the MVC Method

How? Do you understand what is meant by MVC, friend? To make it clearer, here’s an example of using MVC through the CodeIgniter framework quoted from the page:

  • Download CodeIgniter then extract the files to your web server.
  • Create a folder model previously so that user data can be captured into the database. Next, add this code:
MVC is
  • Next, create a new folder for controller with a different name from the model folder earlier. And add the following code:
MVC is
  • Then for display views, create a new folder again and add this code:
MVC is
MVC is
  • Finally, try accessing on localhost to see and test the results. And it will look like this:
MVC is

That’s the review about the MVC concept, a method with complex components that is often used for website development. Judging from the various benefits and advantages, it never hurts to start implementing the MVC method on your website. How, interested in trying it?
