I think you are right, and we should go with suggested algorithm. Here is
an example:
Manager -> (1) Department -> (many) Empolyee
would give a flattened to-many relationship of "Manager.employeeArray"
(Though Manager is also an Employee, and this makes this circular, I can't
think of a better example).
