Is there any method to let 2 disconnected graphs in the same database in Neo4j communicate together?
Hi @familylife103 and welcome to the Neo4j Community!
You could take a look at Neo4j Fabric, which maps multiple databases within a Neo4j DBMS into a logical group of graphs, which can then be queried.
See Fabric Graph Database: Getting Started with Neo4j Fabric
