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
