Neo4j
Graph Database
• Property graph data model• Nodes and relationships
• Native graph processing• Cypher query language
Property Graph Model Components
Nodes • The objects in the graph • Can have name-value properties • Can be labeled
Relationships • Relate nodes by type and
direction • Can have name-value properties
