ObjectDB is an Object Oriented Database Management System (ODBMS). It provides all the standard database management services (storage and retrieval, transactions, lock management, query processing, etc.), but it uses an object oriented model to store and manage data . You can easily store ordinary

To access relational databases using the Java Persistence API (JPA) you will need an Object Relational Mapping (ORM) tool, such as Hibernate, TopLink, EclipseLink, Open JPA or DataNucleus. The DataNucleus ORM implementation supports also the Java Data Objects (JDO) API. ObjectDB is a full featured

You can use ObjectDB with either the Java Persistence API (JPA) or the Java Data Objects (JDO) API. Both share similar architecture, design and abilities. When to prefer JPA JPA is more commonly used. Therefore, it might be the first choice for most new applications. You can use JPA as
