WHAT IS MVC? APPLICATION OF MVC MODEL IN PROGRAMMING
MVC model is one of the names that you can’t know when accessing web programming. If you haven’t understood about this programming pattern, this article of Hachinet is absolutely a knowledge manual that you need!
What are the MVC model and its components?
MVC is shortened by 3 words Model – View – Controller. This is a design model used in software technology. Source code model into 3 parts, corresponding to each word. Each word corresponds to a separate activity in a pattern.
To understand more, let’s interpret and analyze each component.
MVC model and its internal components.
Is a part that stores all the app’s data. This part also is a bridge between 2 components below View and Controller. The model illustrates in the form of a different database, or simply is a normal file XML. The model clearly shows operations with the database such as allowing view, processing data, accessing, etc.
These are themes for users, where users can access the MVC’s information and data through accessing like searching or using via the website.
Normally, apps use MVC View like a part of the system, where HTML components are created. Besides, View also records users’ activities to interact with the Controller. Yet, View doesn’t have any connection with Controller as well as can’t take data from Controller, just showing the request transferring to the Controller.
For example, the “delete” button is created by View when users click it, it’ll have action inside the Controller.
This part will solve users’ requests via view. From there, C gives the data relevant to the user. Besides, the Controller also has the function to connect with the model.
The flow of interaction between components in MVC.
For example, the function of adding the news on the website administration page. There are 2 input fields for the title and content of the article, which:
- The View will display the title and content form input.
- Controller gets data from 2 fields and sends it to Model.
- This model will receive data from the Controller to store in the database.
Each part performs certain functions, yet they are united, linked together that create MVC patterns. This model is relatively light. It can integrate with many of the features that are present in ASP.NET today, such as authentication.
How does the flow go in the MVC model?
You can imagine when a request from the client machine is sent to the server, the controller will do its function to receive and comply with that request. In a necessary situation, it can contact Model - the department that works with the database for support.
After the request is processed, the result will be returned to View. The view will build HTML code into the interface and display it in the browser.
Pro and con of MVC
The advantages of the MVC model
Light, saving bandwidth: MVC doesn’t use ViewState so it will save spaces on bandwidth. When using, users can use apps on websites needing to interact and receive data continuously. Therefore, reducing bandwidth helps the website operate better and more stable.
Pro-con of MVC model
- Easily checking: With MVC, you can easily check and check software errors before reaching consumers, ensuring higher quality and credibility.
- View and size: View will be the place to store the data. The more requests are made, the larger the file size. Meanwhile, the network connection also reduces load speed. Using the MVC model will help you to save the bandwidth optimally.
- Soc (Separation of Concern) function: This function allows you to separate parts such as Model, interface, data, business.
- Interoperability: The integration in the MVC model allows you to freely write code on a website platform. Meanwhile, your server will be offloaded quite a lot.
- Simplicity: This is a model with a relatively simple structure. Even if you don't have too much expertise, you can use it.
The disadvantages of the MVC model
MVC is usually used in some big projects. Therefore, with small projects, MVC models can be huge, a waste of time on the development process as well as data transferring time.
Apply the MVC model to programming
MVC models are applied for many different programming languages, but the most popular is the ASP.NET app or PHP MVC.
MVC is currently a model applied a lot in programming.
A well-developed MVC system will allow front-end, back-end development on the same system without the interference, sharing, or editing of files while one or both parties are still working.
The use of the model is relatively simple. Just need to understand the operating process, grasp the functions of each part, then deploying the MVC model is relatively easy.
Those above are some basic knowledge about MVC models. Hope the article by Hachinet will help you better understand MVC and its application effectively.
