Stage 4: Build the conceptual model and taxonomies
Knobit of Data modelling · K-421 · Skill
Models a role as an association to the party playing it
What it means
Replaces kind-of links that fail all-and-some for roles (customer, supplier) with the party-role pattern.
How it is assessed
Roles are not subclasses of the party; a role superclass holds the shared role attributes; cardinality lets a party hold several roles over time
