However one can explore graphs in SQL if the relationship has all three of the mathematical properties needed for an equivalence relationship.

NEO4J, the graph database, can be used to provide answers that are very tricky for relational databases, including providing diagrams to show how SQL tables relate to each other, and the shortest chain of relationships between two tables, as David Poole demonstrates
