What is the purpose of the Model-View-Presenter (MVP) pattern in Liferay?

The Model-View-Presenter (MVP) pattern plays a crucial role in establishing a clear separation between user interface logic and business logic within an application. This architectural pattern is designed to enhance maintainability and testability by organizing code into distinct components.

In the MVP pattern, the "Model" represents the data and business logic of the application, the "View" is responsible for rendering the user interface, and the "Presenter" acts as an intermediary that handles the communication between the Model and the View. By doing so, the Presenter can contain the logic to update the View without directly embedding business logic within it. This allows developers to modify or test the View independently of the underlying logic, leading to a more organized and efficient codebase.

Furthermore, the clear separation that MVP provides helps in implementing unit tests, as the Presenter can be tested in isolation without requiring a complete user interface. This is particularly valuable in Liferay, where maintaining the flexibility and scalability of web applications is essential.

Other aspects mentioned, such as connecting different layers of the application, facilitating database communication, or managing user sessions, are important in application design but do not encapsulate the primary intention of the MVP pattern. While those functionalities might be part of an application’s architecture
