This is an excellent application of the JavaBean matching
capability. Basically, what you'll want to do is to write a (fairly
trivial) JavaBean class for each relation which reflects the columns
of that relation. The Jess defclass command will then generate the
deftemplates automatically from
I'm interested in this topic, too and have given it a bit of

beholder) solution would have four parts:

problem. In a large database, this is just not acceptable. And the
property change issue is non-trivial also since databases (at least
the ones I
