What is wrong with this model It is in three pieces of 39, 4 and 4 that do not touch, so a question starting in one and ending in another has no path whatever the data underneath looks like. Nineteen entities have no relationship at all and sit in their own band at the bottom rather than being hidden. Twenty seven entities carry 46 reference fields that name no target, drawn as short gold stubs; each one is a relationship somebody meant to write down and did not.
