Started Development: First Week of May, 2001 (10-15hrs/week)
Assignment Submitted: Tuesday, July 24, 2001
Written Exam: Thursday, July 26, 2001
Score Received: Tuesday, July 31, 2001

Design
RMI selected and tracked client id's. I modified the lock and unlock methods. Modification of records without locking was forbidden. Locking methods removed from Data class and moved to data server.
Data Server: Operations by unregistered clients are forbidden. None of the methods on the server were marked as synchronized. Mutual-exclusion was enforced in synchronized blocks that attempted to gain monitor-locks on specific instances/fields. Server program created as a command line tool that included ability to view client and lock information on the server side. Also, allowed administrator to break stale locks.
GUI: Simple, cleanm, and included images. Used a tool-bar that launched dialog boxes for each specific user action.
Why (I think) I lost points:
Used Visual Age for GUI design. I think I lost points on ther server becuase I moved lock/unlock to another class. I also had several mis-spellings in my design document.
I've been developing with Java for a while, I'm going to start learning other languages like C++. Are there any sites that are to C++ as javaranch is to Java? Hope this helps. All questions welcome.
