4. What we learned

Technical

• How to use gdbm. gdbm's interface is simple and elegant and was very easy to learn.
• How to use strtok_r. Trivial extension to strtok().
• How to use java sockets. We used them as buffered streams, which made the interface to the network very simple and clean.
• How to use awt to construct a usable gui. We had to expand into the Event handling routines. Swing would have been a nice touch.
• How to organize server code effectively by using a dispatcher function that parsed input and passed control to handler functions.
• Learned how to use setjmp() to make intelligent signal handers. Allowed for clean database shutdowns on ^C.

Collaborative

• Meeting with multiple teams to discuss overall needs would have been better than meeting as needs arose.
