The document discusses different MV* software design patterns - MVC, MVP, and MVVM. It explains the basic structure of each pattern, including how the view, controller/presenter, and model components interact. It provides examples of each pattern, including links to sample applications. The key benefits of these patterns are also summarized, such as separation of concerns, easier testing, and independence of the UI from business logic.

8. Why

9. Separation into layers
During the development process,
developers and designers can
work more independently and
concurrently on their components.
The designers can concentrate on
the view they can easily generate
sample data to work with, while
the developers can work on the
view model/controller/presenter
and model components.

10. Easy test creation
The developers can create unit
tests for the view model and the
model without using the view.
The unit tests for the view model
can exercise exactly the same
functionality as used by the view.

11. UI independency from
business logic (MVVM)
It is easy to redesign the UI
of the application without
touching the code because
the view is implemented
separately. A new version of
the view should work with
the existing view model.

12. Adaptor
If there is an existing
implementation of the model that
encapsulates existing business
logic, it may be difficult or risky to
change. In this scenario, the view
model acts as an adapter for the
model classes and enables you to
avoid making any major changes
to the model code.
