Models a role as an association to the party playing it
Mida see tähendab
Replaces kind-of links that fail all-and-some for roles (customer, supplier) with the party-role pattern.
Kuidas seda hinnatakse
Roles are not subclasses of the party; a role superclass holds the shared role attributes; cardinality lets a party hold several roles over time
