1. Introduction to MVC
- multidimensional controller (Model-View-Controller) is a design pattern widely used in systems, especially web applications. This model helps create intuitive and highly interactive user interfaces. MVC divides the application into 3 main parts, each with a separate role:
structure:
- Model: Obtain data from storage such as databases, web services, content providers, etc. and provide it to controllers or views.
- view: is what is displayed to the user on the screen. Users interact with View through the following actions: pressing buttons, scrolling through lists, viewing photos, playing music…
- controller:Includes all logical processing. It receives requests from View and obtains data through Model as needed. Then process the data and return to View to display the results to the user.

2. When to use MVC?
- When you need to display data in different ways or have multiple ways to interact with it.
- When there is a need to clearly separate interface, application logic, and data for easier maintenance and scalability.
3. Advantages of MVC
- Segregation of duties: Allow data changes without affecting the interface, and vice versa.
- flexible:Supports the same data to be displayed in different ways.
- Reuse: Components can be reused more easily.
4.Disadvantages of MVC
- When an application has only simple logic, complexity increases.
- Additional code is required to manage interactions between components.
