如何通过neo4j中的第三个节点对两个相关的节点建模? [英] How to model two nodes related through a third node in neo4j?

问题描述

我正在学习Neo4j，目前正在白板上考虑我所想的场景. 我有3个产品P1，P2，P3. P1和P2是独立产品. P3是可帮助您连接P1和P2的适配器.

I'm learning Neo4j and currently whiteboarding the scenario i'm thinking of. I have 3 products P1, P2, P3. P1 and P2 are standalone products. P3 is an adapter that helps you connect P1 and P2.

我想到了P1-[connects_to]-P2，其中P3是connects_to关系的属性，但是那我怎么存储P3的属性呢? 如果我将所有三个产品都创建为节点并执行P1-[connects_to]-P3和P2-[connects_to]-P3，则这并不真正代表域. 如何在Neo4j中对此建模?

I thought of P1-[connects_to]-P2, with P3 as a property of the connects_to relationship, but then how'd I store P3's properties? if i create all three products as nodes and do P1-[connects_to]-P3 and P2-[connects_to]-P3, that's not really representative of the domain. How do i model this in Neo4j?

推荐答案

我认为您可以使用类似的模型:

I think you can use a similar model:

(P1)-[:connected_through]->(A:Adapter)<-[:connected_through]-(P2)

(A)-[:type_is]->(P3)
