1. Week 1 INFM 718N Web-Enabled Databases The Big Picture

2. Agenda Teaching theater orientation Why do this? Architecture Tools Course design Term project

3. Teaching Theater Login –University password and ID Tech support Notes –RTF for Word, Powerpoint for printing Video –RealVideo + Videotape

4. Looking at Examples Explore one Web-enabled database (7 min) –Work in 10 teams of 2 people each –Identify features you like and dislike Report to the class (1 minute!) –Very briefly describe it Content, control, presentation, policies –Say one new thing you like, one that you don’t

5. Database Server-side Programming Interchange Language Client-side Programming Web Browser Client Hardware Server Hardware (PC, Unix) (MySQL) (PHP) (HTML, XML) (JavaScript) (IE, Firefox) (PC) Business rules Interaction Design Interface Design Relational normalization Structured programming Software patterns Object-oriented design Functional decomposition

6. Model: An Abstraction of Reality Formal –To permit automated reasoning Necessarily incomplete Useful for a purpose

7. Upside Data reuse Multiple views Scalability Personalization / access control

8. Downside Brittle –Depends on 3 servers Complex –Learning, design, implementation, debugging Formally modeled

9. Languages and Protocols Web –Standards:HTTP / (X)HTML / URL –Software:Server, Browsers Database –SQL Programming languages –Server-side: PHP, Perl, JSP, ASP.NET –Client-side: JavaScript, Java Data interchange –XML / DTD

10. Tools WAMP (for PC) –PHP 5.1.2 + MySQL 5.0.18 + Apache 2.0.55 –GUI tools OTAL (Sun Unix) –PHP 5.0.5 + MySQL 4.1.15 + Apache 2.0 Text editor/Integrated Dev. Environment –Eclipse, emacs, notepad, …

11. Introductions Pair with someone you don’t know Briefly interview each other –Name and what program they are in –One interesting thing about them –One thing they want to learn from this class Take a 10 minute break Introduce them after the break –30 seconds per person!

12. Controlling What Computers Do Process design –Logic errors Algorithm design –Run-time errors Coding –Syntax errors

13. Programming Skills Hierarchy Reusing code [run the book’s programs] Understanding patterns [read the book] Applying patterns [modify programs] Coding without patterns [programming] Recognizing new patterns

14. Three Big Ideas Functional decomposition –Outside-in design High-level languages –Structured programming, object-oriented design Patterns –Design patterns, standard algorithms, code reuse

15. Installing WAMP http://www.en.wampserver.com/ Run phpinfo.php –Error reporting on? MySQL configured? Create a database and user accounts (mysql) Run mysql_test.php –Connects OK?

16. Working with PHP Local vs. server-based display HTML as an indirect display mechanism “View Source” for debugging Procedural vs. Object-Oriented

18. Learning Strategies Weekly class sessions –Ways of thinking –Mixed-initiative interaction (questions, teamwork) Readings –Exposure to ideas, details, and references Structured exercises –Points of departure for experiential learning Project –Experiential learning, mastery of details Mailing list and optional TA “lab sessions” –Student-initiated interaction

19. Grading Project: 80% –Team grade: 40% –Your management role: 20% –Your technical role: 20% Homework: 10% –PHP, MySQL 5% each Participation: 10% –Class sessions, mailing list

20. Term Project Optimally 3-person teams –You pick ‘em, you live with ‘em! –Minimum of 2 (severely limits what can be done) –Max of 4, but only for Ajax teams Must solve a real problem for a real client –But don’t over-promise! No configuration/language limitations

21. Preparing for the “Idea Rally” A 90-second “elevator pitch” –One interesting and feasible idea –Plus why they should want you on their team! –Showing one optional powerpoint slide Illustrate your point, don’t say the same words! One-page handout (22 copies) –Your idea in a short paragraph –Your name, picture and contact information –A list of your strengths

22. First Things First Functionality Content Usability Security/Stability

23. One-Minute Paper What was the muddiest point in today’s class? Be brief! No names!
