>> 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.
