Thank you so much. I have a midterm in an hour on these topics in databases. My professor explained the theory behind disjoint and overlapping but did not show us how to show this in LucidChart. This was exactly what I needed to know! You're awesome.
For a total relationship you would connect two plain lines from the superclass to the circle. For a partial relationship, just use one. It might depend on your instructor or organization, however, so you may want to check with them as well.
