MVC Architecture
The Model-View-Controller (MVC) architecture is a popular choice for websites. It helps us keep our code in order. It mandates that the three main parts of any application or program be the data model, the display data, and the control data. For the MVC pattern to work, it is necessary to break out all these parts into their own objects.
The MVC framework’s structure is described in depth below:
The MVC design pattern is used in MVC-based model designs to partition the application functionality from the user interface. The MVC pattern has three levels, as suggested by its name:
- Model: represents the business layer of the application
- View: defines the presentation of the application
- Controller: Manages the flow of the application
Let’s see each other's components in detail:
View
The portion of an app responsible for showing information to users is called a “View.”
The information from the model is used to construct the views. A view polls the model for data and then shows the user-facing presentation according to what it receives.
Charts, graphs, and tables are also included to complete the picture. For instance, all user interface elements like text fields, drop-down menus, and so on are included in every customer view.
Controller
The Controller is the part of the program that processes requests from the user. The controller decodes the user's mouse and keyboard movements before relaying that information to the model and view.
The model’s state is updated in response to instructions from a Controller (such as “Save this document”). In addition to modifying its appearance (for example, by scrolling a document), the controller can issue commands to the view it is associated with.
Model
The model section maintains information and related rules. It stands for information that is being passed around among controller parts or relevant business logic. For instance, a Controller object can access customer data directly from the backend. Data is manipulated before being either sent back to the database or rendered.
It acts in response to requests from the views and follows the controller’s instructions for updating itself. This pattern’s lowest level is also responsible for data maintenance.
Advantages of MVC Architecture in Java
MVC architecture offers a lot of advantages for a programmer when developing applications, which include:
- Multiple developers can work with the three layers (Model, View, and Controller) simultaneously
- Offers improved scalability, that supplements the ability of the application to grow
- As components have a low dependency on each other, they are easy to maintain
- A model can be reused by multiple views, which provides reusability of code
- Adoption of MVC makes an application more expressive and easy to understand
- Extending and testing the application become easy
You can see why MVC has become the standard in web development. But if you’re still having trouble wrapping your brain around MVC, that’s okay. Please see the accompanying documents.
