CS561 HOMEWORK #2

Assigned: Thursday, Jan 25, 2007
Due: Thursday, Feb 1, 2007

To do:

• Most importantly, project1 on developing an ORDB application is out. I suggest you make sure to spend time on this early on as you may encountered unexpected obstacles down the line.

• Last week we have discussed adding OO features to a database model. We focussed primarily the impact of this addition on data modeling and applications.
  For this week, again review your OODB/ORDB readings. Then aim to identify the main implementation/system techniques of the underlying database management system that are affected by this model change. Examples of such services that may need to be enhanced or replaced include query processing, transactions, indexing, storage, etc. Try to organize your thoughts, in some written notes would be most advisable, so that you can contribute to the discussion in class. However, I'll not collect any written homework from you on this.

• Read the assigned readings on triggers and rules in database management systems. They are linked into our course webpage. This week I'll not collect a written critique on these readings, as we'll be spending at most 1/2 of the class on this topic. However, for the following week, you will be writing a critique on this material -- so you can start thinking about this now.
