Flex

Flex is a free, open source framework for building highly interactive, expressive web applications that deploy consistently on all major browsers, desktops, and operating systems. It provides a modern, standards-based language and programming model that supports common design patterns.

MXML, a declarative XML-based language, is used to describe UI layout and behaviors, and ActionScript™ 3, a powerful object-oriented programming language, is used to create client logic. Flex also includes a rich component library with more than 100 proven, extensible UI components for creating rich Internet applications (RIAs), as well as an interactive Flex application debugger.

Why use Flex?

  • Rich User Experience
    Applications developed using Flex ensure rich user experience through intuitive interaction with the application and presenting information in a visually rich interface. The end compiled output is Flash which is the most ubiquitous client software worldwide.

  • Quick ResponseFlex allows development of applications that support complex business logic to run at the browser, rendering a feeling of "quick response" and no refresh.
     
  • High PerformanceThe highly evolved client environment of Flex allows the applications to process large amount of information at client-end without any noticeable change in performance of the applications. This is in contrast to conventional DHTML applications which routinely crash if the record set is scaled up.
     
  • Advanced Client-Server Interactivity
    Flex enables advanced interactivity between client and server allowing high performance data transmission. This makes Flex an ideal RIA framework for enterprise applications
     
  • Diverse Modes
    Flex supports diverse modes of presenting data with an integrated development model for complete customization and control. Applications developed with are highly customizable and make the most of Flex to deliver complex customers needs
     
  • Common Model
    Flex brings innovation in a common development and design model. Flash is no more a "designers only" tool.
     
  • Strong Development Model
    Flex offers a strong development model that combines ActionScript and MXML.
