  1. Web Applications 1 An Introduction WA

  2. The Team • Details of your team here

  3. The Lectures • Introduction • Recap on web pages / Web Standards / • Further CSS and XHTML/Intro To XML • Sever side Scripting • ASP.net • Accessibility • Methods for web design • Usability / Design • Devices and browsers • Security

  4. We want you…… • …to build useable web applications • …to build database backed web sites • ASP .NET (provide support / server space ) • JSP • PHP • …to understand what is associated with enterprise web apps

  5. We don’t want…

  6. Tutorials / Practical • Tutorials • 2 a week

  7. Attendance Philosophy • Must attend lectures • Must attend tutorials

  8. Assessment • Exam (40%) • 45 Minutes – Short Answer & MC • Assignment (60%) • Two parts – report and implementation • Demos

  9. Implementation • Produce a dynamic web application (55%) • 15 screens. • A site that is valid to XHTML and CSS standards • The majority done by server side scripting using databases. • A search engine showing elements of information drill down / sideways / querying / searching. • An element of personalisation or globalisation. • An example of web site administration. • A style that is consistent, appropriate and useable for the target audience applying techniques for the effective design of a web site • An element of Innovation / Originality. • This will be assessed by demo. Your site should run with Internet Explorer, Netscape Navigator and Firefox.

  10. Report • A fully referenced report of approximately 3000 words plus appendices which includes the following (35%) • An introduction on what your site is about, and its aims. • An analysis of the needs of the target audience it is aimed at. • An investigation into systems analysis and design methods and their appropriateness for database backed web sites. • An application of appropriate methods, tools and techniques to produce a design for your web site and underlying database. • A discussion of the reasons behind your choice of content and style for that target audience, and why your site is appropriate and useable for the target audience.

  11. Report • A critical evaluation of the usability of your site, having tested the usability of your site using 5 people and usability techniques. • A discussion of the issues you would face in deploying your application in the real world and any associated maintenance overheads. • The appendix should also include • Produce an ERM for the underlying database. Produce storyboards and a flow chart using the principles shown in the lecture. Add these to the appendix of your report. (10%) • Details of your usability testing process and the results obtained.. • Printouts of the screens and a printout of the compliancy to standards

  12. Books • No core books • Will recommend books for some topics for further reading • Will recommend web sites for further reading

  13. Any Questions?????? – Before the recap

  14. What is a Web Page / Web Site? • Web Page • A page that is viewable via a browser • Can contain various components • http://www.soc.staffs.ac.uk/flk1/web/ • Web Site / Web Application • Collection Of Web Pages of related content

  15. Web Development – Dependant On • Author expertise - Solid programmer or non/low programmer • Purpose of the web-pages • Simple static pages • Advanced / dynamic pages • The tools you choose to create your pages determine and dictate what can be achieved • We are looking at functional usable pages…

  16. Design based Functional

  17. Visual First • Visual impression is the main issue - emphasis on an eye-catching site • Known as ‘Brochureware’ or ‘Introware’ • Page incorporates a large media element on the page (e.g. ShockWave or Flash) • Difficult to update, generally have to re-edit or replace the media lump • Lacks any technology behind the ‘Glitz’, limited in functionality, but can select and navigate in movie - can be slow • Not really looking at this sort – more like advanced web multimedia

  18. Function First • Sites that are intended to be less visual and carry out specific function or functions • Generally the focus of what most businesses want • Information gathering, getting in details from users • Pages of information to present to the user • Sales to customers, e.g. e-commerce applications • Portal Sites • Database driven • Not aimed just at the broadband market • The sort of site we are looking at…

  19. Browser orientated design (Technology First) • Sites designed specifically to map to the latest browser version • Also known as ‘Exclusive design’ i.e. you design specifically to include the latest gimmicks and plug-ins of a latest browser release • An approach that utilises the latest facilities and can be very adventurous in what is achieved • However, older and alternate browsers can not handle your design correctly, if at all • Need to trade-off between being advanced and viewable • Should avoid for functional sites…

  20. Web Editors • Visual Studio .net • Dreamweaver • FrontPage • Visual Interdev • Web Matrix • Notepad • Etc…etc…..

  21. Web Matrix

  22. Visual Studio .NET

  23. What’s the editors do… • Which ever editor you use. it produces the script either directly or indirectly • Web pages will always be at some stage in a form of script….

  24. What Is Scripting? • Small-embedded programs • Usually quicker and easier to write than conventional languages • Client Side • XHTML • JavaScript • WML • Server Side • ASP / ASP .NET • JSP • PHP

  25. The Standards • Set by World Wide Web Consortium – W3C – www.w3.org • Main thing pages are written in is HTML (hopefully moving towards XHTML) • More about this next week…

  26. The Browsers • Main player is Internet Explorer • But not the only player • Netscape • Opera • Mozilla / Firefox • Etc…. • http://www.ddj.com/documents/s=2728/nam1012432163/index.html • http://hotwired.lycos.com/webmonkey/reference/browser_chart/ • http://browsers.evolt.org/ • http://www.anybrowser.com/ • http://www.w3schools.com/browsers/default.asp
