A key-value store with other data models and querying apis layered over top, so you can treat the same data as relational (with sql queries) and graph (with gremlin traversals) at the same time. WHAT. Indexes as a data model, like in document databases.
“neo4django is a Django ORM integration for neo4j. It allows model definitions that are very similar to Django’s, and enables some other Django functionality (like signals). The original Neo4j Django integration restricted database access to in-process. neo4django uses the Neo4j REST api to communicate with the database, freeing the database up for access by other processes and making it easy to host the database on another machine.”
