Summary

object-oriented programming

[] readme course preface 1 2 3 4 5 6 7 8 9 10 11 12 appendix lectures resources
This chapter discussed the relevance of object-oriented technology to the development of Web-applications.

Objects and the Web

1


slide: Section 12.1: Objects and the Web
 In section 1, we looked at trends and technologies, in particular the ongoing creation of the ObjectWeb, which is essentially an ongoing war between Microsoft and the rest of the world.

Programming the Web -- a search for APIs

2


  • models of computation
  • intelligent agents
slide: Section 12.2: Programming the Web -- a search for APIs
 In section 2, we discussed the model of computation underlying the Web. We looked at the requirements we may have for APIs, and we explored the notion of intelligent agents on the Web,

The DejaVU experience -- jamming (on) the Web

3


  • animating the Web -- an SGML-based approach
  • bringing music to the Web -- data formats + client-side plugin
  • jamming (on) the Web -- additional communication servers
slide: Section 12.3: The DejaVU experience -- jamming (on) the Web
 In section 3, some of the research efforts carried out in the DejaVU project were presented. In particular, we looked at an SGML-based approach to extend the Web with new media and communication facilities.

Architecture revisited

4


  • OO -- simple call and return
  • CORBA -- independent components
  • WWW -- data centered
  • events -- independent components
  • logic -- virtual machine architecture
slide: Section 12.4: Architecture revisited
 Finally, in section 4, we discussed some remaining architectural issues. We concluded that many of the applications discussed in this book draw from a mixture of technologies and architectural styles.

Questions
  1. Describe the architecture of the Web. Explain the relevance of objects for the Web.
  2. Sketch the Microsoft approach to the ObjectWeb. Discuss its pros and cons.
  3. In what ways can Java and CORBA be deployed in Web applications?
  4. Indicate how the computation model underlying the Web deviates from the computation models underlying, respectively, object systems and client-server systems.
  5. What requirements can you think of for libraries or frameworks for developing Web applications?
  6. Discuss the Document Object Model.
  7. What are the requirements for a framework supporting intelligent agents?
  8. Explain the issues that arise in extending the Web with additional media functionality. What solutions can you think of? Can you give an example?

Further reading

For information concerning the Web, have a look at www.w3c.org which give a detailed account on the history of the Web and many other issues. For an exposition of the issues and technologies that play a role in the battle for the ObjectWeb, consult  [OWSurvival]. A good introduction to agents and its associated technology is given in  [Survey]. For architectural issues, again, I recommend  [Practice].
