This is not my area, and I am too lazy to ask someone. However, I
think a number of Gemstone customers use Coco Base from Thought,
Inc. and I have heard of some using TOPLink from Object People. I
would expect those tools to provide the mapping back and forth instead
of customers writing it themselves.
As for maintaining coherency back to the app server from third party
changes to the DB... I think the complexity of that is going to depend
on specific customers' environments. Using triggers might have their
own scalability and integrity issues. You probably want to do that
stuff outside the database, per se. Which is why you would use an app
server in the first place?
Remember to KISS.
