OrientDB：边缘VS LinkList vs Linkmap [英] OrientDB : Edges vs LinkList vs Linkmap

问题描述

使用 linklist ，a linkmap 或者使用边来存储我的顶点之间的关系？

解决方案

边定义两个顶点之间的关系。例如，你定义了两个顶点Person和Car。然后您定义一个边缘驱动器。该边将两个顶点连接在一起。 Jane驱动Ford。

链接列表是与另一个类关联的类的列表。 Car类可能有Part类的部分链接列表。一辆车由多个部分组成。

linkmap是与另一个类关联的关键类值的映射。汽车类可能有PartType的部分链接图。一辆汽车由多个部分组成，可以按发动机，车身，底盘等分组。

What are the pros and cons for using either a linklist, a linkmap or an edge to store relationships between my vertices ?

解决方案

An edge defines a relationship between two vertices. For example, you define two vertices, Person and Car. You then define an Edge Drives. This edge ties the two vertices together. "Jane" Drives "Ford".

A linklist is a list of classes associated with another class. A Car class might have a linklist of parts from the Part class. A car consists of multiple parts.

A linkmap is a map of key, class values associate with another class. A car class might have a linkmap of PartType, Part. A car consists of multiple parts, which can be grouped by engine, body, chassis, etc.
