MVC Pattern: An Overview

The MVC (Model-View-Controller) pattern is a design pattern widely used in software development to separate the concerns of an application into three interconnected components:

1. Model:
   • The Model represents the data and the business logic of the application.
   • It is responsible for managing and manipulating the data, ensuring its integrity and consistency.
2. View:
   • The View is responsible for presenting the data from the Model to the user.
   • It handles the user interface elements, ensuring a clear and visually appealing representation of the information.
3. Controller:
   • The Controller acts as an intermediary between the Model and the View.
   • It receives user inputs from the View, processes them, and updates the Model accordingly.
   • The Controller contains the application’s business logic, making decisions about data manipulation and processing.

   

Model

Simply put, the Model encapsulates the data and business logic of the application. It ensures that the data remains consistent and is manipulated according to the rules defined by the application.

View

The View focuses on the presentation of data to the user. It creates a user-friendly interface, displaying information from the Model. Importantly, the View is designed to be passive and should not directly manipulate the data.

Controller

The Controller serves as the orchestrator, managing the flow of information between the Model and the View. It interprets user inputs, updates the Model, and ensures that the View reflects any changes. Additionally, the Controller houses the application’s business logic, promoting a modular and maintainable architecture.

In summary, the MVC pattern provides a structured approach to software design by separating the concerns of data, presentation, and control. This separation enhances the modularity, maintainability, and scalability of software projects.
