I've just found a series of YouTube clips by Jonn Howell, posted in 2010, from Bootcamp for Filemaker 2010.
In one clip, Jonn talks about data modeling. He was about to explain two ways to approach modeling three entities, Staff, Company and Phone (multiple companies, lots of staff and many phones), when the clip ended! I've been unable to find the continuation of his talk. Would anyone know if thereis a part two and where to find it?
I'm trying to get my head around a very similar problem and thought he might have the answer...
