Model–view–viewmodel (MVVM) is an architectural pattern in computer software that facilitates the separation of the development of a graphical user interface (GUI; the view)—be it via a markup language or GUI code—from the development of the business logic or back-end logic (the model) such that the view is not dependent upon any ...
The observer design pattern is a behavioural pattern listed among the 23 well-known "Gang of Four" design patterns that address recurring design challenges in order to design flexible and reusable object-oriented software, yielding objects that are easier to implement, change, test and reuse.
The MVC pattern subsequently evolved, [11] giving rise to variants such as hierarchical model–view–controller (HMVC), model–view–adapter (MVA), model–view–presenter (MVP), model–view–viewmodel (MVVM), and others that adapted MVC to different contexts.

Windows Presentation Foundation (WPF) is a free and open-source user interface framework for Windows-based desktop applications.WPF applications are based in .NET, and are primarily developed using C# and XAML.
The following is an example of a simple Hello World program. The @main attribute defines the entry point into the app. It is standard practice in SwiftUI to separate the application struct and views into different structs, according to the Model–View–ViewModel (MVVM) architectural pattern.
The component diagram extends the information given in a component notation element. One way of illustrating a component's provided and required interfaces is through a rectangular compartment attached to the component element. [3]
The structure of an application with PAC.. Hierarchical model–view–controller (HMVC) is a software architectural pattern, a variation of model–view–controller (MVC) similar to presentation–abstraction–control (PAC), that was published in 2000 in an article [1] in JavaWorld Magazine.
