Q1Domain Verified
In the context of graph data modeling and Neo4j Cypher, when modeling a relationship with properties, which of the following Cypher constructs is *most* appropriate for representing the relationship and its associated attributes?
`(node1)-[:RELATIONSHIP {property: 'value'}]->(node2)`
`(node1)-[:RELATIONSHIP]->(node2); INSERT PROPERTY ON RELATIONSHIP node1.id = 1, node2.id = 2, property = 'value'`
`MATCH (node1), (node2) WHERE node1.id = 1 AND node2.id = 2 CREATE (node1)-[:RELATIONSHIP]->(node2) SET node1.property = 'value'`
`(node1)-[:RELATIONSHIP]->(node2) {property: 'value'}`

Consider a graph model for a social network where users can "FOLLOW" each other. If you need to store the date when one user started following another, how would you best represent this in Cypher, focusing on efficient querying for "who followed whom before a certain date"?
Store the follow date as a property on the "user" node that initiated the follow.
Create a separate "FOLLOWED_ON" node for each follow event and link it to both users.
Use a temporal data type directly within the node labels to indicate follow dates.
Store the follow date as a property on the "FOLLOWS" relationship.
Q3Domain Verified
You are modeling a supply chain where "PRODUCTS" are manufactured by "FACTORIES" and shipped to "WAREHOUSES". A "SHIPMENT" relationship connects a "FACTORY" to a "WAREHOUSE", and this shipment has properties like `quantity` and `ship_date`. If you want to find all products that were shipped from a specific factory before a certain date, what is the most efficient Cypher pattern to consider?
`MATCH (f:Factory)-[s:SHIPMENT]->(w:Warehouse)-[:CONTAINS]->(p:Product) WHERE f.name = 'FactoryA' AND s.ship_date < '2023-01-01' RETURN p`
`MATCH (f:Factory)-[:SHIPMENT]->(w:Warehouse) WHERE f.name = 'FactoryA' AND w.id IN (SELECT id FROM Shipments WHERE ship_date < '2023-01-01') MATCH (w)-[:CONTAINS]->(p:Product) RETURN p`
`MATCH (f:Factory {name: 'FactoryA'})-[s:SHIPMENT]->(w:Warehouse) WHERE s.ship_date < date('2023-01-01') MATCH (w)-[:CONTAINS]->(p:Product) RETURN p`
`MATCH (f:Factory {name: 'FactoryA'})-[:SHIPMENT {ship_date: date('2023-01-01')}]->(w:Warehouse)-[:CONTAINS]->(p:Product) RETURN p`
