    Study Notes

    Working with Laravel

    • Laravel is a framework for building web applications.
    • It uses the Model-View-Controller (MVC) design pattern.

    MVC Pattern

    • A widely used architectural pattern in software development.
    • Separates application concerns into interconnected components.
    • Model, View, and Controller.
    • Improves maintainability and facilitates collaboration.

    Model

    • Handles all data-related logic.
    • Represents application data and business logic.
    • Encapsulates data operations (retrieval, manipulation, validation, storage)
    • Interacts with the database, responds to controller requests.
    • Independent of user interface.

    View

    • Responsible for all user interface logic.
    • Generates user interface.
    • Receives data from the Model (through the Controller).
    • Renders data in a suitable format (e.g., HTML).
    • Separates visual representation from business logic.

    Controller

    • Connects the View and Model.
    • Processes user input and performs actions.
    • Updates the Model and View accordingly.
    • Decides which Model methods to invoke, and which View to render.
    • Orchestrates interactions between components.

    Logic of MVC Pattern

    • The server receives an end-user request.
    • The server sends it to the appropriate controller.
    • The controller requests data from the model.
    • The model retrieves data from the database.
    • The controller passes the data to the view.
    • The view renders the data and returns it to the user.

    Key Principles and the MVC Pattern

    • Separation of Concerns: Isolates different aspects of an application.
    • Modularity and Reusability: Enhances maintainability and scalability.
    • Testability: Easier to write unit tests for components.
    • Parallel Development: Allows teams to work on different components concurrently.

    Advantages of MVC

    • Easy to maintain and extend.
    • Model components can be tested separately.
    • Reduces complexity.
    • Supports Test-Driven Development (TDD)
    • Works well for web apps with large development teams
    • Search Engine Optimization (SEO) friendly

    Disadvantages of MVC

    • Can be difficult to read, change, or reuse.
    • Not suitable for small applications.
    • Inefficient data access in the view.
    • Complex framework navigation; new layers of abstraction to adapt.
    • Increased complexity and data inefficiency.
