What is MVP architecture?

Model-view-presenter (MVP) is a software architecture design pattern that was originated by Taligent ( a software company) in 1990. Software architecture design patterns improve systems by dividing complex codes into smaller, maintainable, and independent ones with specific tasks or functions.

It is similar to the MVC architecture, but the presenter replaces the controller. The presenter is responsible for data communication between the model and the view. Below is an illustration of how the model and the view communicate data through the presenter.

MVP components

The three components of MVP are model, view, and presenter. Below, we will briefly look into what each of the components is responsible for:

Model

The model is responsible for fetching and storing data in databases using APIs. It encapsulates database operations, network communications, and other business-related logic. The core application's logic resides in the model independent of the UI interface.

View

The view does not contain any business logic and is responsible for displaying user interface elements that the user interacts with. It displays data from the model in a visually appealing format, keeps track of user activities, and sends them to the presenter.

Presenter

The presenter is an intermediate between the view and the model responsible for data communication. The presenter takes user input from the view and performs processing on it. It then interacts with the model to update or fetch data. It is also responsible for changing the view depending on the changes caused by the model.

Benefits of MVP

The benefits that MVP architecture provides are:

1. Separation of concerns: MVP separates the responsibilities of data management, business logic, and user interface rendering that increases code modularity and maintainability.

2. Testability: MVP promotes testability by decoupling the components. Developers can perform unit testing separately on the model, view, and presenter, making testing easier and faster.

3. Code reusability: With MVP, developers can reuse the business logic in the presenter and data manipulation operations in the model across different views. This improves code efficiency and reduces redundancy.

4. Enhanced collaboration: The separation of concerns in MVP enables parallel development between UI designers and developers. UI designers can focus on creating system views while developers work on the core business logic in the presenter and data management in the model.

MVP is usually used in Windows Forms applications and ASP .NET form applications. The selection of the software architecture design pattern depends on the system's requirements.
