>> acyclic database scheme? <<

I assume that they mean a schema in which the referenced and referencing integrity do not form cycles. The classic example is a constraint set that says "you cannot get a job until you have experience" and "You cannot get experience until you have had a job", so that the schema does not let anyone in it.
