Neo4j is a native graph database that uses nodes, relationships, properties, and labels to represent data in a graph structure. It supports the ACID transaction model and can handle millions of operations per second. Neo4j uses the Cypher query language to match graph patterns and allows data to be queried and visualized as a graph. It also supports clustering, scaling, high availability, and integration with official drivers.

Property Graph Model Components
Nodes
• Represent the objects in the graph
• Can be labeled
Relationships
• Relate nodes by type and direction
Properties
• Name-value pairs that can go on
nodes and relationships.

6. Summary of the graph building blocks
• Nodes - Entities and complex value types
• Relationships - Connect entities and structure domain
• Properties - Entity attributes, relationship qualities, metadata
• Labels - Group nodes by role
