CS561 "HOMEWORK" #7

Assigned: Thursday, Mar 15, 2007
Due: Thursday, Mar 22, 2007

To do:

• Read the assigned readings on RFID data management systems. I have handed out copies in class, and they are also linked onto our webpage.

• Prepare one integrated written report on all three readings to be turned in in the next class meeting. Given that this is a single critique on three papers, I would expect that it will be larger in terms of content and scope than just one page.

• The goal is to tease out the main points from the assigned readings.

• Topics to consider in your critique include:
  • Explain what are the main challenges raised by RFID data management; divide those into "stream-specific" and "general (static) data management" challenges.
  • Briefly sketch the one (or at most two) most important ideas proposed in each of the papers, respectively.
  • We have already discussed general approaches taken for supporting query processing against dynamic data streams. Now, in the current set of readings, these data streams are assumed to be generated via physical devices such as RFID readers or other such sensor types. Discuss, what if any, issues specific to devices such as RFID tags may now arise -- beyond generic stream processing challenges.
• Can you think of any research challenges beyond those tackled in those 3 papers that remain unsolved to date?
