There's not such a thing. The closest thing might be virtual nodes but I don't think that's what you're actually wanting here.
I feel as if you might be trying force an RDBMS model to fit into a graph database. I recommend instead of trying to do a one-to-one mapping of a table in MySQL into graph, think about the graph data model that would be needed to support the application, then transform the data from the SQL source to match the graph model.
@mike.r.black Thank you.
May I ask you incite on Master-Detail Relationships? Am going to study the Northwind example and shall follow up on another post: Transferring from MySQL Master Detail individual records to Neo4j nodes (denormalization)
