Rich Internet Applications (RIA)

• By 2010 60 of new applications will include
  Rich Internet Applications (RIA)

• Rich Internet Applications
• Delivered over the Web
• Lower TCO than thick client
• Look, feel and perform like
  desktop software GUIs
• Higher efficiency than html pages
• Richer functionality than html pages
• Best of Both

Desktop Responsiveness
Rich GUI Stateful Event Driven

Ajax Architecture Strategies

• Enriched HTML pages
• Hardwire
• Communications and data to DOM with procedural
  JavaScript
• Replace with new server generated HTML DOM chunks
• Two Pass Parse and Replace
• DHTML replacement of tags in HTML page after
  the first load of the page
• JavaScript manipulation of DOM and JS Objects
• Ajax RIAs
• Object based JavaScript Applications
• Communication with services

Four Quantum States of Ajax

• A,J,,X
• All about communications. Wheres the GUI?
• DHTML Widgets
• Enabled with async-communications (maybe)
• Multi-Widget Libraries
• Shared underlying services
• Rich Internet Application Frameworks
• Common GUI, data, communication framework
• Ability to visually author GUIs more

Erosion of Desktop OS

• Ajax RIA minimizing the differences
• Real-time data
• Offline apps
• The good enough factor
• Firefox and Adobe will continue to press
  Microsoft to provide parity with its browser
• OpenAjax Alliance driving core standards
