As data becomes more and more variable the data itself becomes the ERD. See www.xdb1.com/Example/Ex102.asp for a solution to a similar problem where persons belonging to a baseball team have multiple roles (manager, coach, player), have different properties (bat avg and position for players), properties (ie phone#) have multiple values and players belong to multiple teams (astros and rangers).
