  3. Agenda • Article discussions • Cao et al (design factors) • Berry (web teams) • Web page coding demonstrations and exercise • Simple forms exercise • Dynamic pages • Server-side scripting • Client-side scripting • As time permits: • Review guidelines for HTML source code • Bulleted lists in HTML • A discussion of web server concepts • Martin & Nguyen team • Additional comments

  4. Now, Discussion of the Assigned Articles • Cao et al  Design factors • Brawley/Bray/Martin/Nguyen team • Other remarks • Berry  Web teams • Batten/Harper team • Other remarks

  5. A Look at Dynamic versus Static Pages • Start the following • Internet Explorer (open your SuSE1 site) • SmartFTP • NotePad • A static page: www.suse1.astate.edu/~flory/page2_proc.html • A dynamic version: www.suse1.astate.edu/~flory/page2.html www.suse1.astate.edu/~flory/page2_proc.html • Exercises & demonstrations • Forms exercise / server-side scripting demo • Forms exercise / client-side scripting exercise & demo

  6. Web Servers • Discussion led by Martin & Nguyen • Other comments • What’s actually happening • Static vs dynamic pages  the reality • 3-tier architectures • Correction • Dynamic content: either client-side or server-side • “Server-side scripting” and “dynamic page-generation” • The major server-side scripting engines • Not really the problem apparent in the textbook • However, XML is a major player in moving into the future • Wrap data of all sorts for display in diverse environments • AJAX • LAMP vs Win vs Sun • What does “open source” really mean?

  7. eMail Comments • Note: our concern is primarily from the sender side • Know the law (CAN-SPAM) • Following guidelines can help immensely • Still, we also need to know how to protect our organizations, whether online or just IT-enabled • Filters • Incoming mail • Outgoing mail (consider ASU vs AOL case) • Accounting naming – TAMU example: students vs staff • Barracuda demonstration

  8. Website Utilities • Simple but powerful utilities • ping • tracert • finger • Data analysis of server logs: Analog • Link checking: FrontPage, DreamWeaver, . . . • Remote administation: TightVNC; FrontPage (!)

  9. A Little More HTML (If Time Available) • Review the guidelines • Bullet (i.e., unordered) lists • Simple forms

  10. Summary of Objectives • Define what’s meant by “web server” • Compare and contrast the top two web server programs • Describe what’s important in choosing a computer to serve as a web server • Compare and contrast static and dynamic web pages • Describe what’s involved with a 3-tier and n-tier architecture • Summarize the major issues associated with email • Discuss factors that result in effective ecommerce websites • Describe the responsibilities of the members of a web team • Use HTML to create bullet lists and simple forms on web pages

  11. Appendix

  12. Browser/Server Interaction

  13. Three Tiered Internet Database Access Architecture

  14. eMail Guidelines • Follow standard Netiquette • Mixed case • Subject lines • Other . . . • Getting around spam filters • Avoid attachments; post to websites and use links • Limit the number of addressees • Send to one at a time

  15. Some Guidelines for Source Code • Use lowercase for tags & attributes • Quote attribute values • Use relative references for resources on same server • Always use closing tags • Nest elements properly; close in reverse order of opening • Use indentation consistently and to make code readable • No more than 80 characters per line of code; break long tags into multiple lines, typically one per attribute • Avoid deprecated elements, e.g., <font> • Use no spaces in file names • Treat all URLs and other resource names as if case-sensitive
