Decoding MVC Architecture : Blueprint for Streamlined Software Development

MVC stands for Model-View-Controller and is a software architecture pattern commonly used to develop software applications. Although originally designed for desktop computing, MVC has been widely adopted as a design for World Wide Web applications in major programming languages.

Components of MVC :

1. Model : -

• Represents the data and the business logic of the application.

• It directly manages the data, logic, and rules of the application.

• The model is responsible for interacting with the database, performing calculations, and ensuring data consistency.

• Example: In an e-commerce application, the model could be responsible for retrieving product data from a database.

2. View : -

• This is the user interface or the presentation layer.

• It displays the data from the model to the user and sends the user’s input to the controller.

• The view only handles the presentation and is not concerned with the underlying business logic or data.

• Example: In a weather app, the view is responsible for showing the current weather, temperature, and forecast.

3. Controller : -

• Acts as an intermediary between the Model and the View.

• It processes user input from the View, updates the Model, and then updates the View with new data.

• Example: If a user clicks on a "Submit" button, the controller handles the input, updates the model (perhaps saving data to a database), and then updates the view to show the result.

How MVC Works ???

• User Interaction: The user interacts with the interface (View).

• Controller Response: The Controller interprets the input, updates the Model.

• Model Update: The Model performs business logic and updates the data.

• View Update: The View is updated with the data from the Model and rendered to the user.

Benefits of MVC : -

• separation of Concerns: Each component is independent, making it easier to manage and scale the application.

• Reusability: The same Model can be used with different Views, and multiple Views can present the same Model.

• Maintainability: Code is more modular, making it easier to update and maintain.
