->The sort of minimal information we are interested in is name, producer and

The strongest one I am aware of is Progress, from Progress Software.

Things I would call integrity are:
	automatic transaction scoping and backout;
	dictionary validations expressions for:
		each field;
		record deletion;

The runtime distribution for Progress is fairly inexpensive; the development
system is not.  You may want to check your local rep:
