ObjectDB vs Neo4J

What are the main difference apart from the JPA. Can ObjectDB provide the same Graph functionalities.

Regards.

ObjectDB is an Object Oriented Database and Neo4J is a graph database. These are different DBMS models with different abilities. As an object oriented database, ObjectDB provides also some graph functionalities, but probably not all the functionality of a pure graph database. On the other hand, object oriented aspects such as inheritance, persisting objects directly into the database and retrieving them from the database, are probably supported better by ObjectDB.
