Week 1 - COAP 3180

Topics Covered

(1) Introduction

(2) Web 2.0 vs. "traditional Internet"

  • An ever increasing amount of applications are available through the Internet. Many of these applications can be shared, others are by definition "social software" (e.g. wikis, YouTube, flickr, blogs).
  • Reading: O'Reilly Tim (2005), What is Web 2.0, better take the print version.
  • Additional resources for those who want to explore this topic further: This wiki, e.g. start from the rich internet application article.

(3) Simple on-line database services

  • Learn how to create and use simple tabular databases with a web 2.0 service
  • Practical details are explored in class and through homework one.

Classroom activities and homework

Synopsis:

(1) Take an account with Zoho (see also below)

(2) Take an account with Netvibes (see also below)

  • http://netvibes.com
  • Create a new page (tab)
  • Import the result view from Zoho
  • Export this page to the public

Homework 1

  1. Think about a little database (list) of things that you would like to put on the web. Then make a list of properties that describe such a "thing".
    • Examples: A list of CDs, a list things you want to sell, your favorite list of flowers
  2. Implement a Zoho creator database that allows to describe each item with a few properties (fields)
  3. Add some test data to this database. Revise the database definition if needed.
  4. Enter some more data (at least 5 items)
  5. Make the Zoho application that displays the result public (gathered data becomes public on the web)
  6. If you wish, you also can make data gathering public
  7. Create a public NetVibes page and import your Zoho creator widget (Advanced course participants may use another environment that allows insertion of widgets, talk to the instructor)
  8. Add an explanation using some NetVibes widget, i.e. describe what your pagecast is good for
  9. Add some useful extra information to the Netvibes page (or equivalent), i.e. the Pagecast should now include the Zoho database plus some useful extra information.

Note: If you prefer to remain anonymous, do not leave Name, Firstname, professional email etc. or anything that can identify you on the public page.

Tips on how to do this are below.

Submission Dates

  • This homework is due at start of Wednesday week 2 lesson
  • Students must provide the URL (where the instructor can see the widget) in the world classroom
  • Each homework counts 10% in your global evaluation. The four best homeworks will be taken into account.

Evaluation

  • Task completion (all required elements are present)
  • Quality of Zoho database (but don't make it too big !)
  • Quality of Netvibes pagecast

Tip: Quality is essentially related to the idea that your applications are useful to a given range of users.

Tips for the homework

Leave all the needed applications open in your browser

Make sure that you are logged to both applications.

  • Netvibes with your login
  • Zoho: Switch to Zoho Creator

Tip: It is best to work with 3 different web browser tabs: One for Netvibes, one for Zoho, and one for this page. If necessary, ask the instructor to explain tabbed browsing...
