discourage duplication of information if it can be avoided. name is a
special case - it helps mappers to quickly identify what the object
represents. If we duplicated everything, than each part of a railroad
station should have duplicate web site URL, hours of operation, operator
name, and tons of other info. Having duplicates lead to inconsistencies,
harder to maintain, etc. For example, if two parts of the station have
different hours of operation - is that a mistake (someone forgot to update
both), or is it intentional? Which one of two is correct? Having a rule to
keep common info in a relation unless it is different makes data more
valuable and less error-prone.
