Neo4j

Neo4j is the company behind the world's most widely deployed graph database. It stores data as nodes and relationships rather than rows and tables, which makes connections - the part most databases treat as an afterthought - the main event. Used by a large majority of the Fortune 100 and a community of more than 250,000 developers, Neo4j powers fraud detection, recommendation engines, supply-chain analysis, and, increasingly, the knowledge graphs that ground generative AI in real facts (GraphRAG).
