What the Graph
summary
Neo4j data modeling as nodes and relationships is explained, and Neo4j OGM with Spring Data Neo4j is shown for mapping domain classes, running Cypher queries, and managing sessions and transactions. A quickstart demo loads about 5 million nodes and performs graph traversals, highlights where OGM handles CRUD and relationship mapping safely versus when custom Cypher or manual mapping is faster, and points out session/transaction pitfalls and constructor-mapping limits; examples run against local and cloud sandboxes.
