Directed relationship
a connection between A and B where the relationship has an arrow flowing from a source to a target, from an origin to a destination, and the relationship means differently in each direction, with (A, B) being distinct from (B, A) in mathematical notation
Why This Is a Definition
This definition clearly establishes the term 'directed relationship' by naming it, stating its genus (connection between A and B), and providing its differentia (arrow flow, directional meaning, ordered pair notation). It distinguishes directed from undirected relationships and uses precise mathematical language consistent with the curriculum's treatment of graph theory.
