Neo4j OGM is a fast object-graph mapping library for Neo4j, optimised for server-based installations and utilising Cypher via the transactional HTTP endpoint. Neo4j-OGM aims to simplify development with the Neo4j graph database and like JPA, it uses annotations on simple POJO domain objects. Together with metadata, the annotations drive mapping the POJO entities and their fields to nodes, relationships, and properties in the graph database.
