Now, all that stuff is fine and dandy, but rows in Postgres don't just exist all on their lonesome; they belong to a table. Neo4j requires every mutating operation on the graph to be run in a transaction, which is great, because it keeps your data safe. Every operation is atomic, consistent, isolated, and durable. As a bonus, Neo4j gives you the opportunity to react to these mutations right before they are committed, or right after they have been committed. Being a graph database, Neo4j is not serving data in a relational way, nevertheless thanks to this driver it’s possible for projects that are using the classic JDBC connector in the relational paradigm to interact with Neo4j.
