MVVM Pattern
MVVM (Model-View-ViewModel) is a design pattern commonly used in software development, particularly in the context of user interfaces (UIs) for desktop and mobile applications. It is a variation of the MVC (Model-View-Controller) pattern that simplifies UI development by separating the UI into three distinct components: the Model, the View, and the ViewModel.
MVVM Components
The Model, as the name suggests, represents the underlying data and business logic of the application. It is responsible for managing data, performing calculations, and interacting with external systems if necessary.
The View, on the other hand, is the visual representation of the data provided by the Model. It handles the UI elements, such as textboxes, buttons, and images, and allows users to interact with the application.
The ViewModel acts as a bridge between the Model and the View. It exposes the data and functionality of the Model in a way that is easily consumable by the View. The ViewModel transforms the data into a format suitable for the UI, handles user interactions, and updates the Model accordingly.
