UI data binding is a software design pattern to simplify development of GUI applications. UI data binding binds UI elements to an application domain model. Most frameworks employ the Observer pattern as the underlying binding mechanism. To work efficiently, UI data binding has to address input validation and data type mapping.
A bound control is a widget whose value is tied or bound to a field in a recordset (e.g., a column in a row of a table). Changes made to data within the control are automatically saved to the database when the control's exit event triggers.
<TextBlockText="{Binding Username}"/>
publicclassExampleViewModel{publicstringUsername{get;set;}}
Swing is a GUI widget toolkit for Java. It is part of Oracle's Java Foundation Classes (JFC) – an API for providing a graphical user interface (GUI) for Java programs.
In software engineering, the terms frontend and backend refer to the separation of concerns between the presentation layer (frontend), and the data access layer (backend) of a piece of software, or the physical infrastructure or hardware. In the client–server model, the client is usually considered the frontend and the server is usually considered the backend, even when some presentation work is actually done on the server itself.
A web developer is a programmer who specializes in, or is specifically engaged in, the development of World Wide Web applications using a client–server model. The applications typically use HTML, CSS and JavaScript in the client, PHP, ASP.NET (C#), Python, Node.js, Go or Java in the server, and http for communications between client and server. A web content management system is often used to develop and maintain web applications.
Extensible Application Markup Language is a declarative XML-based language developed by Microsoft that is used for initializing structured values and objects. It is available under Microsoft's Open Specification Promise. The acronym originally stood for Extensible Avalon Markup Language, Avalon being the code-name for Windows Presentation Foundation (WPF).
Windows Forms (WinForms) is a free and open-source graphical (GUI) class library included as a part of Microsoft .NET, .NET Framework or Mono Framework, providing a platform to write client applications for desktop, laptop, and tablet PCs. While it is seen as a replacement for the earlier and more complex C++ based Microsoft Foundation Class Library, it does not offer a comparable paradigm and only acts as a platform for the user interface tier in a multi-tier solution.
A web framework (WF) or web application framework (WAF) is a software framework that is designed to support the development of web applications including web services, web resources, and web APIs. Web frameworks provide a standard way to build and deploy web applications on the World Wide Web. Web frameworks aim to automate the overhead associated with common activities performed in web development. For example, many web frameworks provide libraries for database access, templating frameworks, and session management, and they often promote code reuse. Although they often target development of dynamic web sites, they are also applicable to static websites.
State management refers to the management of the state of one or more user interface controls such as text fields, OK buttons, radio buttons, etc. in a graphical user interface. In this user interface programming technique, the state of one UI control depends on the state of other UI controls. For example, a state managed UI control such as a button will be in the enabled state when input fields have valid input values and the button will be in the disabled state when the input fields are empty or have invalid values. As applications grow, this can end up becoming one of the most complex problems in user interface development.
In computer programming, data binding is a general technique that binds data sources from the provider and consumer together and synchronizes them. This is usually done with two data/information sources with different languages as in XML data binding and UI data binding. In UI data binding, data and information objects of the same language but different logic function are bound together.
A single-page application (SPA) is a web application or website that interacts with the user by dynamically rewriting the current web page with new data from the web server, instead of the default method of a web browser loading entire new pages. The goal is faster transitions that make the website feel more like a native app.
Model–view–viewmodel (MVVM) is a software architectural pattern that facilitates the separation of the development of the graphical user interface – be it via a markup language or GUI code – from the development of the business logic or back-end logic so that the view is not dependent on any specific model platform. The viewmodel of MVVM is a value converter, meaning the viewmodel is responsible for exposing (converting) the data objects from the model in such a way that objects are easily managed and presented. In this respect, the viewmodel is more model than view, and handles most if not all of the view's display logic. The viewmodel may implement a mediator pattern, organizing access to the back-end logic around the set of use cases supported by the view.
Backbone.js is a JavaScript library with a RESTful JSON interface and is based on the model–view–controller application design paradigm. Backbone is known for being lightweight, as its only hard dependency is on one JavaScript library, Underscore.js, plus jQuery for use of the full library. It is designed for developing single-page web applications, and for keeping various parts of web applications synchronized. Backbone was created by Jeremy Ashkenas, who is also known for CoffeeScript and Underscore.js.
AngularJS is a JavaScript-based open-source front-end web framework for developing single-page applications. It is maintained mainly by Google and a community of individuals and corporations. It aims to simplify both the development and the testing of such applications by providing a framework for client-side model–view–controller (MVC) and model–view–viewmodel (MVVM) architectures, along with components commonly used in web applications and progressive web applications.
Ember.js is an open-source JavaScript web framework, utilizing a component-service pattern. It allows developers to create scalable single-page web applications by incorporating common idioms, best practices, and patterns from other single-page-app ecosystem patterns into the framework.
Webix is a JavaScript/HTML5/CSS3 UI toolkit for developing complex and dynamic cross-platform web applications. The framework is developed by the IT outsourcing company XB Software, headquartered in Minsk, Belarus.
React is a free and open-source front-end JavaScript library for building user interfaces or UI components. It is maintained by Facebook and a community of individual developers and companies. React can be used as a base in the development of single-page or mobile applications. However, React is only concerned with state management and rendering that state to the DOM, so creating React applications usually requires the use of additional libraries for routing, as well as certain client-side functionality.
jQWidgets is a software framework with widgets, themes, input validation, drag & drop plug-in, data adapters, built-in WAI-ARIA accessibility, internationalization and MVVM support. It is built on the open standards and technologies HTML5, CSS, JavaScript and jQuery. This library is used for developing responsive web and mobile applications. Some developers consider jQWidgets one of the top alternatives to the open-source jQuery UI.
NativeScript is an open-source framework to develop mobile apps on the Apple iOS and Android platforms. It was originally conceived and developed by Progress. At the end of 2019 responsibility for the NativeScript project was taken over by long-time Progress partner, nStudio. In December 2020 nStudio also oversaw the induction of NativeScript into OpenJS Foundation as an Incubating Project. NativeScript apps are built using JavaScript, or by using any programming language that transpiles to JavaScript, such as TypeScript. NativeScript supports the Angular and Vue JavaScript frameworks. Mobile applications built with NativeScript result in fully native apps, which use the same APIs as if they were developed in Xcode or Android Studio. Additionally, software developers can re-purpose third-party libraries from CocoaPods, Maven, and npm.js in their mobile applications without the need for wrappers.

Meteor Blaze is a powerful library for creating live-updating user interfaces. Blaze fulfills the same purpose as Angular, Backbone, Ember, React, Polymer, or Knockout, but is much easier to use. We built it because we thought that other libraries made user interface programming unnecessarily difficult and confusing.
