This blog series explores how Neo4j and Oracle RDBMS can work together to deliver optimal results for enterprise architects and business teams. Migrating or syncing a subset of data from Oracle to Neo4j can be beneficial, especially when dealing with complex relationships that cannot be efficiently answered by the current application. Two approaches are discussed: migrating relevant data to Neo4j as a transactional ACID-compliant data store, and synchronizing a portion of the data with Neo4j using middleware such as Oracle GoldenGate. This approach has been successfully implemented by Norwegian telecom Telenor, who synced their resource authorization data with Neo4j, enabling real-time login capabilities for users. The benefits of this approach include faster login times, reduced latency, and improved scalability.
