Connectivity to Neo4j Graph database

Hi,

My data resides in Neo4j graph database. I need to connect to Appian and build a relational DB based on this graph data model.

Is there a direct connectivity possible to achieve this? I'm looking for a direct integration from neo4j to Appian in the form of connectors or ETL tool or API's.

Please let me know. Any help appreciated.

Thanks,

Sonia
