Rich Internet Applications - Rich vs. Reach RIA The best of both worlds!! Deployed over the Web No installation or automated installation and updates Look and feel of desktop applications Lots of choices: Lightweight Ajax Heavyweight Ajax Browser-based Plug-ins Desktop RIA

Lightweight Ajax Focused on Ajax-ifying a traditional Web application Open source JavaScript libraries – over 150 Most popular Dojo YUI (Yahoo) jQuery Prototype ExtJS Simplifies programming Hide browser differences Ajax controls and visual effects XML helper functions XMLHttpRequest object

Heavyweight Ajax Focused on building a complete Ajax UI or significant independent UI component Client Written in JavaScript or compiled to Javascript Server Compilation services Framework services Database integration Web services and REST support Data compression/normalization Limited visual designer tools Commercial open source offerings with up-sell

Heavyweight Ajax – Programming Models Declarative XML with JavaScript Backbase (no server) Nexaweb Tibco General Interface (no server) OpenLaszlo (no tools) SmartClient ASP.NET/JSP Use a native programming language, e.g. C#, VB.NET, Java At runtime converted to HTML and JavaScript GWT (Google) Program and debug in Java Compile to JavaScript

Browser Plug-ins Adobe Flex Runs on Flash player Program using MXML and Actionscript – compiled to SWF Built-in RPC, REST, Web Services, and server-push mechanism via optional LiveCycle Data Services Flex Builder (Eclipse plug-in) provides visual designer Silverlight (Microsoft) - V3 released July 2009 Program using XAML and a .NET programming language like C# or VB.NET Silverlight specific visual designer Communicate with the server using WCF, e.g. REST, Web Services, sockets Supported on all IE, Firefox, and Safari browsers and Windows, Mac, and Linux platforms

Desktop RIA OpenEdge GUI for .NET or OpenEdge GUI with WebClient Windows only Adobe AIR Flex on the desktop Released Feb 2008 Supported by SalesForce and ebay Windows, Mac, Linux Microsoft WPF/Winforms with ClickOnce Windows only Java UI with Java WebStart (limited momentum)

Number of User Interfaces – May 2008

Percent Usage by UI Type

OpenEdge GUI for .NET And OpenEdge GUI Percent Usage by Deployment Type

Matching The Usage Intensity Persona Groups To Ajax Deployments

OpenEdge RIA Strategy and Positioning End-user Satisfaction

Summary Don’t succumb to the hype Start with the end-user Ajax for occasional user and infrequent user Browser plug-ins and desktop RIA for power users Factor in the skillsets of the developers Follow the guidelines and principles of the OERA Plan for the future http://communities.progress.com
