🕸️Neo4j

NEW

Native graph database platform optimized for storing and querying relationships using the property graph model.

DESCRIPTION

Neo4j is a widely used graph database that models data as nodes, relationships, and properties. Its declarative query language Cypher simplifies pattern matching over connected data. Neo4j supports ACID transactions, clustering, and graph analytics via the APOC library and Graph Data Science. Use cases include fraud detection, recommendations, network analysis, and knowledge graphs. It offers both open-source and enterprise editions with cloud managed options.
