In Neo4j, you could model the same scenario by representing users and groups as
nodes

relationships
are, unsurprisingly, the relationships or connections
between nodes. The plain English sentence that corresponds to this diagram is “A person
belongs to a group.”
Let's see how that looks with several people, and several groups (

)
