Understanding MVC (Model View Controller) Architecture

In the world of software development, architecture plays a crucial role in building robust, maintainable, and scalable applications. One such popular architectural pattern is the Model View Controller (MVC) architecture.

MVC architecture provides various benefits :

•Clear separation of data, presentation, and control logic.

•Easier maintenance and code reusability.

•Supports the development of large and complex applications.

•Enhances overall software quality and reliability.

Understanding MVC (Model View Controller)

• Model: The model serves as the central hub for our business logic, where all the relevant operations take place. It interacts with the model databases to access the necessary data. Within the model, we carefully prepare the business logic, process it, and generate the desired output, which is then seamlessly passed on to the controller for further handling.

• View: It manages the presentation layer, handles the user interface, and presents data to the user. It routes requests to the controller, which then pushes them to the model layer for processing. Acting as a bridge, the view facilitates communication between the user interface and the model layer, ensuring seamless interaction within the application.

• Controller: The controller acts as the initial defense for incoming requests, directing them to the appropriate destinations. Its primary role is to receive user requests and forward them to the models for processing. While the controller does not handle business logic, it ensures smooth data flow between the view and the models.

  Understanding the Working of MVC (Model View Controller) Architecture

• The Crucial Role of the Controller is the First Line of Defense in MVC Architecture

• Model Facilitating Database Interactions and Defining Data Storage Structure in MVC Architecture, ensuring efficient and accurate operations for products and relevant entities.

• The repository manages database interaction logic, while the model defines entity structure and behavior. The repository handles tasks like user creation for efficient database interactions, while the model specifies user representation and attributes. This approach ensures organized data management and interactions in the application.

• The service layer plays a crucial intermediary between controller and repository, encapsulating business logic and coordinating data operations for modularity and maintainability.

• Helper layer: Facilitating retrieval of external data to complement and enhance application functionality beyond the database.

  Explaining all concepts of MVC architecture with an example :

  • When booking a movie ticket, the request is initially handled by the controller. The desired date, time, and theater for the ticket are specified. The controller performs essential checks to ensure availability, such as verifying seat availability, theater show availability, and ticket price. It then displays a seat map showing the remaining available seats.

    Upon confirming the booking, the service layer comes into action. It fetches data from the repository, specifically targeting the particular theater and time, and it determines the current seat availability status. Once the necessary data is retrieved, the service layer proceeds to initiate the payment process by interacting with the payment gateways.

    This seamless flow of operations, from initial request handling by the controller to data retrieval and payment processing by the service layer, ensures a streamlined movie ticket booking experience.

Setting Up MVC Architecture

• In MVC architecture, there are two ways to set up the folders.

  a) Task-based: It is commonly employed for small-scale projects. A key practice involves grouping files with similar tasks into the same folder, promoting organization and clarity.

  b) Feature-based: This is predominantly utilized in big, complex projects, particularly within large companies. This architectural pattern offers ease of management, allowing for efficient handling of intricate project structures and workflows.
