Tutorial #21

Note: Bendigo students taking this subject in semester 1, 2001 -- this tutorial is combined with tutorial 22 in a single session.

  1. Can you think of any other forms of electronic commerce than those mentioned in today's lecture?

  2. What is Electronic Data Interchange? How is it different to the Internet and Unix electronic mail facilities you have used?

  3. Describe three (or more) advantages of using EDI compared to manual systems. Do any of these seem more important than others?

  4. Describe the three key components of an EDI system. Are all three of these necessarily going to be required in every EDI implementation?

  5. What is the significance of each of the X.12 and EDIFACT standards for EDI?

  6. Comment on the EDIFACT message structure. Why is it regarded as somewhat old fashioned?

  7. (Philosophical question) The emergence of the Internet has changed the way in which many businesses do their computer networking. Discuss the options for EDI in the Internet context. Are there likely to be cost benefits from using the Internet instead of a proprietory EDI service? What factors do you think are limiting the use of the Internet for EDI? What does the future hold?
