An association group is a set of attributes that coordinate with each other, in that
each attribute field consists of a list of values, where the first value in the list of one
attribute relates to the first value in the list of the other attributes in the association
group. For example, the association group could have the attributes "Country", "Tariff",
"Currency", and "Measurement". The attribute values for a record might be: Country =
Argentina | Germany | India | United States Tariff = 0.02 | 0.04 | 0.06 | 0.08 Currency =
peso | euro | rupee | dollar Measurement = metric | metric | metric | USCS Where for the
Country "Argentina", the Tariff is "0.02", Currency is "peso", and the Measurement system is
"metric".
