Neo4j Relationships are what connect any two nodes in the graph. To copy paste from the Neo4j guide:
Relationships organize nodes into arbitrary structures, allowing a graph to resemble a list, a tree, a map, or a compound entity — any of which can be combined into yet more complex, richly inter-connected structures.
