I think this is a good idea.  I am trying to learn Smalltalk by writing
a very, very, very simple payroll system.  Most of the book examples
one sees deal with traditional CS problems like counting unique words in
a file, but few deal with that other side of computing.

To do this, I've been trying to build a simple, reusable relational database,
with objects for Relation, Domain, Tuple, and Database.  It will be an in
memory type of toy system, no disks blocks, B-Trees, etc.

What I also need is a ScreenForm object, so I can define a few fields,
flah them up on the screen, let the user fill in the blanks, edit, and either
commit or abort the record/Tuple entry.

I don't have any thing anywhere near ready to post, but I hope some of you
do.  Please post classroom demos, throwaway protottypes, or whatever.

thanks
