What is an Edge?

An Edge defines how two nodes are connected.
Edge Still
If Nodes are the nouns of your context graph, Edges are the verbs. Examples:
  • Customer places Order
  • Order contains Product
  • Employee works on Project
  • Account belongs to Organization
  • Firm invested in Company
Without edges, you only have isolated concepts. With edges, you can answer questions like:
  • Which customers bought this product?
  • Which invoices belong to this account?
  • Who is responsible for this deal?
  • How are these two entities connected?

​
Representing Data as Edges

Nodes define the main entities of your graph. Edges define how those things interact. Edges can represent many kinds of connections. Some examples:
