directed relationship
A relationship that runs one way, from its start node to its end node. Every relationship Neo4j stores is directed.
Also written: directed relationships
Example
(:Person)-[:FOLLOWS]->(:Person) runs from Ava to Ben.
An algorithm or query following the direction reaches Ben from Ava. It does not reach Ava from Ben.
