I am an experienced MS Access developer and I am interested in using
Interbase / JBuilder for future database applications. Despite the
negatives of Access, it has some great features- like being able to quickly
define relationships between tables graphically.

Is there software available to graphically define relationship constraints
in Interbase? I've found software that makes table design easier (built
into JBuilder), but none for relationship constraints. This is more then
just a convenience: When a client wants to see what the database they
bought *really* is, the clearest description is a picture of the tables and
the relationships between them.

Does anyone have some suggestions?

Thanks,

Eric Everman
