Answer one of the following:

  1. This issue was brought up in class, and we really didn’t have time to do it justice: Apple’s model is to tie digital goods distribution tightly to a single platform (the iPad/Pod/Phone and iTunes). Amazon is more flexible, allowing you to buy and view books and music on many different devices (not just the Kindle). From a digital content perspective, which model do you think will ultimately succeed?
  2. Assess the future of the subscription model for digital information goods. In other words, will companies that sell digital content (whether it is music or medical information) be able to collect an ongoing revenue stream? Defend your answer.

Answer one of the following:

  • Most end-users interact with databases through applications (i.e., web interfaces, Windows applications). Security can be enforced in both the database and the application. So where do you think the responsibility for accidential damage should rest – with the application developers or the database administrators?
  • Describe an experience where a lot of data was lost from a database in your organization. Why did it happen? What safeguards, if any, could have been put in place to prevent it from happening?

Answer one of the following:
