What does MVVM stand for in software design?

The correct answer, Model-View-ViewModel, refers to a design pattern commonly used in software development, particularly in applications with a graphical user interface. This pattern separates the representation of information (the Model) from the user's interaction with it (the View), allowing for more manageable and maintainable code.

In the MVVM architecture, the Model encapsulates the business logic and data, the View is responsible for displaying the UI elements and presenting the data to the user, and the ViewModel acts as an intermediary that facilitates communication between the Model and the View. The ViewModel retrieves data from the Model and transforms it into a format that the View can use, handling user input and commands, thereby enhancing the separation of concerns.

This separation is particularly beneficial in applications where complex user interfaces and interactions are involved, as it allows developers to work on the data and logic independently from the user interface, making for cleaner and more modular code. Additionally, it facilitates testing by allowing each component of the architecture to be tested in isolation.

The other options do not align with established patterns in software design, as they either misuse terminology or do not represent recognized concepts in the industry. By focusing on the well-defined roles that each component plays in MVVM, developers can
