ISA diagram for ER sheet

[Stephen Brown <sbrown7 umbc edu>]

Hi All,
	I ended up creating a diagram to represent the IS-A
generalization/specialization relation for a database class -- it is
attached.  Unfortunately, the .png file is grossly blocky... maybe some
kind soul with more development skill than me can repair it.
