relationship in Graph.

A relationship in a property graph always has:

- a direction, (that can be navigated regardless of direction)
- a type,
- two nodes (a start node and an end node if directed).
- quantitative properties (such as weights, costs, distances, ratings, time intervals, or strengths)

An existing relationship will never point to a non-existing node.

A sequence of edges is called a path
