/**
 * The current pk in AdminEntityData and AccessRulesData is a mix of integer pk and 
 * constraints and actually works fine. 
 * It's used like a primitive int primary key in the db, but embeds logic for 
 * enforcing constraints, which would otherwise have to be programatically added to the beans.
 * If needed it can easily be replaced with an int pk and programatic logic to handle 
 * constraints. From the database view the pk is just an int.
