Property graph
A property graph is a graph data model in which nodes and the edges connecting them can have labels and key-value properties.
Graph Algorithms for Data Science
A property graph is a graph model in which nodes and relationships can carry properties and relationships connect nodes rather than other relationships.
- How it is used
- Frames graph modeling as the first step toward querying, descriptive analytics, inferred networks, and graph machine learning.
- How deep it goes
- Defines LPG components, direction, properties, notation, and modeling choices, then stops short of comparing graph models.
- Examples
- Uses people, organizations, friendship, employment, fraud, class hierarchies, and Twitter follower, tweet, and retweet networks.
- What you can do after
- Build it from scratch by translating a domain into labeled nodes, typed relationships, properties, and Cypher representations.

Knowledge Graphs and LLMs in Action
A labeled property graph is a graph data model in which nodes and edges have labels and properties and represent relationships.
- How it is used
- Supports knowledge graphs requiring property-rich representations, efficient traversal, path analysis, and relationship-specific metadata.
- How deep it goes
- Defines nodes, edges, properties, traversal, and RDF contrasts, but stops short of RDF’s advanced semantic capabilities.
- Examples
- Uses a disease–phenotype annotation whose edge stores source, author, and creation date, queried with Cypher.
- What you can do after
- Apply it via Cypher to model entities, attach edge provenance, and retrieve relationship properties through graph patterns.
