If node with id 0 is to be connected to node with id 1 you need to have a relationship with start id 0 and end id 1.

A very simple layout would be:

Nodes: (just id, no properties)

id
0
1
2

Relationships: (just the mandatory fields)

id | start | end
0  | 0     | 1
1  | 0     | 2

This is a graph with three nodes and two relationships.

If you look at the signature of the readFrom method, you can see that it actually takes 1 to n entity tables. In your case, you can just pass in session.readFrom(pickupTable, dropoffTable, tripTable).
