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.
