Model-View-Controller (MVC)
Application Architecture Explained
Model-View-Controller(MVC) is an organizational structure that is used to implement user interfaces, manage data, and control logic. It defines the various sections in your application and the way they communicate with each other. This structure helps to turn complex application development into a much more manageable process.
Sections of MVC
Model: Retrieves and manages data
View: Graphical user interface
Controller: The brain of the application and liaison between the Model and the View. It receives user requests and routes the commands to the view and model sections.
A Real World Analogy
In a restaurant, we have three key components:
- A chef who makes the food
- A waiter who takes the orders from customers and brings the food back to the table
- A table where the food is served to the customer
The model is the chef. This section manages critical aspects of the application such as communicating with the database. The controller is the waiter. This section takes orders from the user and delivers the data to the user. The view is the table. This section renders the data for the user.
Benefits of MVC
- Separation of Concern: Provides for a better division of labor in your application.
- Code Organization: Breaks your client and server-side components into separate sections.
- Allows scalability: Makes it easier to manage and make changes to your application.
- Increased collaboration: Allows several developers to simultaneously work on the application
Conclusion
Modern web applications can be very complex making it essential to incorporate MVC into your projects. The concept behind MVC is to deal with the separation of concern. This is the idea that each section of your application should have a distinct purpose.
