Can Neo4j and SQL combination work together?

Hi,

I'm fairly new to NoSQL databases and hence always have this question about being able to use a Polyglot system where we have a NOSQL db like Mongo/Neo4J/Cassandra along with a relational DB. Hence was wondering if Neo4J has any provision to support this or any transaction support etc or does this have to be managed by the Business logic.

If it is business logic that will manage transactions, lot of ORM frameworks like Ibatis/Abator or Hibernate will not be as useful as they are.

Any thoughts there?

Thanks

Hi Samir,

They certainly can.
Neo4j is ACID-compliant and can participate in XA transactions with supported JDBC connections and/or any other XA resource (JMS connections...)

If you use Spring Framework, Neo4j can participate in transactions using @Transactional annotation as well.

For more details you can take a look at Chris Gioran's blog (a bit old, but still valid in Neo4j XA space):
