DSE图数据库“是”关系表示在groovy

Question

我很难理解这张图。 我明白了

  

Org and Persons是顶点，'有供应商'，'有客户'和'有员工'是边缘，但我无法理解 “isMerchant”的含义 在附图中

名称非常直观，Org属于商家类型，

但是我如何在Groovy中表示相同的内容？

对于边缘

这样的事情

 schema.edgeLabel('Has Vendor').connection('Org',
 'Person').ifNotExists().create()

What is the link for this diagram? Based on the proximity of Merchant to Org and the colors used to denote some "meaning", it appears as if Merchant may be a Property of Org. If that's the case, then simply creating a property for Merchant and adding it to the Org vertex will provide the desired results.

If Merchant is a separate Vertex, then creating an "Is Merchant" edge like what you've described will provide the desired results.
