Example of Microsoft Ajax Application Useful Useful functions functions Integrated Integrated coexisting coexisting applications with applications with Contextual Contextual added value added value actions actionsApplication Application like likebehaviour behaviour Application Application Interactivity Interactivity like like without full without full behaviour behaviour page reload page reload Rating Rating system system 40
  • 41. Key disadvantages of traditional web appsPoor Interactivity Simplistic Interfaces Users must wait for full page The requirement for full page reloads after each interaction with postback whenever the user the server. interface has to be changedSlow & Unresponsive imposes hefty limitations on the Classic web applications transfer degree of sophistication of web the complete form data to the user interfaces. Rich and smooth server, which in turn renders and interfaces with on-demand update sends back the full HTML markup could only be implemented using of the page to the browser. Lots of host technologies bandwidth is consumed and the Wasted Resources performance is significantly Powerful PCs, sitting 99% idle hindered. while sophisticated servers arePoor User Experience compiling multi-dimensional DB We’re 2006, yet most web forms queries AND writing <tr><td>… at look like coming from 1996 the same time 41
  • 42. The rise of the new web“The Web as we know it is changingprobably more than it has since thefirst graphic showed up… The idea ofthe webpage itself is nearing itsuseful end. With the way Ajax allowsyou to build nearly statelessapplications that happen to be webaccessible, everything changes.”Jesse James GarrettFebruary 15, 2005 42

  • 44. Enter AjaxAjax aims to deliver: – Rich applications in browsers – No issues with installation – Built on existing infrastructure: (TCP/IP, SSL, HTTP, XML…)Concept & Mechanics – Acronym stands for “Asynchronous JavaScript + XML”. – The core idea behind Ajax is to make the communication with the server asynchronous, so that data is transferred and processed in the background. – As a result the user can continue working on the other parts of the page without interruption. – In an Ajax-enabled application only the relevant page elements are updated, only when this is necessary. Ajax is a new development technique, not language, Ajax is a new development technique, not language, blurring the line between web-based and desktop applications blurring the line between web-based and desktop applications delivering rich, highly responsive and interactive interfaces delivering rich, highly responsive and interactive interfaces 44
  • 45. Ajax – The detailsMotivation: – HTTP never intended to dynamically serve content – Pages always reload, but never get updated – Users wait for the entire page to load even if a single piece of data is needed – Single request/response restrictions: no middle ground between “this page” and “next page”Describes a simple development pattern – Asynchronously request data from the server – Process the Result – Update the Page – Technology has been around for many yearsVery good for improving form interactionsUsually insufficient by itself for building applications Ajax is a tool (pattern) of many for building rich experiences Ajax is a tool (pattern) of many for building rich experiences 45
  • 46. Direct AdvantagesBetter Performance and Efficiency: Small amount of data transferred from the server. Beneficial for data-intensive applications as well as for low- bandwidth networks.More Responsive Interfaces: The improved performance give the feeling that updates are happening instantly. Ajax web applications appear to behave much like their desktop counterparts.Reduced or Eliminated "Waiting" Time: Only the relevant page elements are updates, with the rest of the page remaining unchanged. This decreases the idle waiting time.Increased Usability: Users can work with the rest of the page while data is being transferred in the background. 46
  • 47. So why is Ajax so hot—NOW?Times are changing It addresses fundamental needs Web2.0 Trend Increase Usability of Web It has a name Applications Recent Google applications have Demand for richer applications is sparked people’s imagination: growing without Flash Google gmail, Google suggests, Save Bandwidth Google Maps Download only data you need Browser Consolidation Faster interfaces (sometimes) Open Standards & Toolkits People are thinking of building Broadband means we can - and APPLICATIONS…not just site want to - do moreThe Tipping Point:The Tipping Point:All of this has made rich internet apps reach its tipping pointAll of this has made rich internet apps reach its tipping pointwhere adoption spreads rapidly and dramaticallywhere adoption spreads rapidly and dramatically 47
  • 48. Is it new?Not ReallyHidden FramesIE5+, Mozilla 1.0+, Safari 1.2+, and Opera 7.6+JavaApplets 48
  • 49. Ajax ApplicationsApplications that have highest benefit from Ajax: Highly interactive, data rich applicationsExamples: Google Spreadsheet: Data visualization – visualizing large datasets Google Maps: Scroll, pan, zoom… all without Flash Data input & validation: it’s possible to validate the data the user enters, while they are entering it. They can then receive feedback (using the server’s intelligence) without the page being posted back. 49

  • 52. After Ajax: Maps 52
  • 53. Ajax is aboutUsability User experience Ease of use Hard to describe Ability to get things done faster Users just get it Measurable Examples Easier to learn – iPod High performance – Google Maps Competitive advantage 53
  • 54. The 8-Hour RuleQuestion: Can your users work with your application for 8 hours a day without getting frustrated?Answer: Traditional web applications fail this rule miserablySolution: Ajax to the rescue 54
  • 55. B2B expectationsToday’s reality Tomorrow’s expectations Applications are complex Applications should become and require a manual to use straightforward; manuals is for advanced features Applications are slow and people Like Amazon, precompile results frequently wait 10-20s for a where possible, use advanced process to finish or a page to load caching techniques and Ajax Forms are just a sequential dump Well structured dynamic forms, of input fields mandatory and optional blocks Fonts are small to compensate for Drill down on details long numbers and long lists Error handling is like “there is an Shift from error reporting to error, please verify your data” proactive handling and solving Telephone numbers are hard to Online contact, messaging, find assistance is on stand-by Business applications and tools should deliver dashboards Business applications and tools should deliver dashboards providing quick access to key data leading to informed decision making providing quick access to key data leading to informed decision making 55
  • 56. UsabilityAn analysis of intranet portals found slimmer informationarchitectures and a renewed emphasis on fresh content and usefulapplications KISS modelThe initial objective/mantra“We need a website”has been replaced by“We need a user friendly and usable website”Arrival of usability groups: – SAP Design Guild – Jakob Nielsen – Governmental guidelines –…Specialized skills – Usability experts ≠ development skills 56
  • 57. Web servicesBefore Now Previously websites had poorly Application providers develop integrated applications (HTML documented web services scrubbing, interface Sites can query web services and redevelopment, poor CSS support, present information a la carte …) Web Services are W3C endorsed Users often bypassed portal to less vendor dependency bookmark service directly (deeplinks) 57
  • 58. Presence based servicesPresence integration – Users can determine the online status of site members quickly by sending e-mail or an instant message, adding the member to a contact list, and viewing current free/busy status.Examples – Show which users are online, and start an instant messaging conversation with them 58
  • 59. CollaborationSolve specific business problems using collaboration tools:Streamline business process with employees and partnersProvide users with contextual collaborationCommunication tools as part of their day by day projectsReduce the pain associated with a proliferation of toolsMerging tools into single environmentBenefit from increasingly rich collaboration platformsProvide tools and let users find an application that helps them intheir normal business process evolution, not revolutionEmbedded collaboration capabilitiesMore built-in support (teamwork, …)Product/platform vendor competitionStrive to push proprietary standards vs open standards makesinteroperability not yet today’s reality 59

  • 138. Ajax building blocksVocabulary HTML and CSS: Presentation, with standardized style informationInterpreted in DOM Document Object Model (DOM) Dynamic display of and interaction with the HTML pageManipulated by a Scripting language Javascript: Client-side code controls actions (controller pattern)Interaction with server XMLHttpRequest object: Asynchronously retrieves data from web server 138
  • 139. Ajax building blocks > Dynamic Object ModelThe DOM exposes a web page to the JavaScript engineTree-structured format – DOM structure well defined byWorld-Wide Web Consortium (W3C) – Each DOM element is a nodeDOM can be read, and also updated (change, insert)Programming recommendations: – Use of “id” attribute to make finding elements easy – CSS styles applied using node’s className attribute: – Use of XHTML 139
  • 140. Ajax building blocks > Asynchronous Data LoadingTwo techniques: IFrames, XMLHttpRequestIFrames (Inline Frames) are an old technique given new life withAjax – Invisible frame, in line with other HTML – IFrame owns the processingXMLHttpRequest: DOM extensions allowing asynchronous callsIssue with both: browser compatibilityDeveloper owns implementation, testing burden…Or we implement using a toolkit and make it someone else’sproblem 140

  • 148. How It WorksFires roughly every keystroke – Uses a timer to determine when to send a request to the server – If you type at “typical” user typing speed—every keystroke – If you type at “programmer” typing speed—every few keystrokesCreates a hidden DIV that is shown when you start typingDIV is populated with return results from serverText field is set to include the next word from the server list andeverything to the right of the cursor position is highlighted – If you hit the right arrow, it assumes you want that text and positions you at the end of the text fieldResults cached; if you backspace, server is not called againHas a timer adjustment to increase or slow down server calls – Slow dialup sessions hit server fewer times – Fast broadband hits a lot 148
