"Generated Design model. Since the term 'model' is so often used already, 'design' was chosen. Model is a better way to understand it. There is a many bundles for each design relationship, so the bundle_id is included. Each design will have a design_role (security, management), design_type (1, 100, 400, etc), and design_subtype (w, g, v, rc, etc). The subtype can be used to determine connection_type (wired, wi-fi, etc)"
