Model View Presenter
Model View Presenter (MVP) is a software architectural pattern that separates an application into three interconnected components: the Model (data and business logic), the View (user interface), and the Presenter (mediator that handles user input and updates the View based on Model changes). It is commonly used in desktop, web, and mobile applications to improve testability and maintainability by decoupling the UI from the underlying logic. MVP is a derivative of the Model-View-Controller (MVC) pattern, with the Presenter taking on a more active role in managing the View.
Developers should learn and use MVP when building applications that require a clear separation of concerns, especially in scenarios where the UI needs to be easily testable or when working on large-scale projects with complex user interactions. It is particularly useful in Android development, desktop applications (e.g., with .NET or Java), and some web frameworks to reduce code coupling and enhance modularity. By isolating the View from business logic, MVP facilitates unit testing and makes the codebase more adaptable to changes in UI design.
