Graph - (Edge | Links | Arcs | Lines | Arrows) - Association

About

An edge model a relationship between two node in a graph. Every edge model therefore a binary relationship (relationship between two elements) .

An Edge is also known as:

A edge 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 edge will never point to a non-existing node.

A sequence of edges between two nodes is called a path
