Hello Teaching staff Could someone please give me an update on my second query from Wed 4th Sept, relationship attributes? The reason for this is that the alternate diagram structures from lesson 4, ER modelling are confusing me. There is an instance of a relationship "Manager start date" that is part of a 1:1 multiplicity, but my research on this topic found that video on the net. Also, I just posted the link for the video and the software wants to put an image there. The guy seems to handle it differently unless he contributes to "stack overflow", where they tend to confuse everybody no end.
