A data model that decides which type of redundancy is good or not is a
limited model. www.xdb2.com/Example/ThingsNamedBrown.asp shows how
multiple things can be named by a single string 'brown'. Changing the
string 'brown' has a gobal effect. Changing the name of thing (ie
person), has the effect of unrelating it from 'brown' and re-relating
to new string (ie 'browne') with effecting existing relationships.
