Neo4j Graph Data Modeling

The property graph model

In Neo4j, we use a property graph model to represent information. The property graph model is an extension of the graphs from mathematics. The following figure gives an example of how data from Figure 1.1 can be represented in Neo4j:

Figure 1.2: Nodes, relationships and properties

The preceding figure introduces the following concepts that we use to model a property graph:

• Nodes: Entities are modelled as nodes. In Figure 1.2, London, Bob, Alice are all entities.
• Labels: These are used to represent the role of the node in our domain. A node can have multiple labels at the same time. Apart from adding more meaning to nodes, labels ...
