In this ERD (0, 1)- ABC and DEF (1,1)- DEF and GHI 1 to 1: ABC/DEF, N to N: DEF/GHI ABC (0, N) to DEF to (1, 1)GHI. GHI? cardinality ratios are used. If instead min/max notation were used, what would be the (min; max) between ABC and DEF? Between DEF and ABC to DEF: (1,1) DEF to GHI: (1, N) 1 "1;1" N "N:M
