ObjectDB Database Search

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

Features 100% pure Java Object-Oriented Database Management System (ODBMS). No proprietary API - managed only by standard Java APIs (JPA 2 / JDO 2). Extremely fast - faster than any other JPA / JDO

The Java Data Objects (JDO) is another standard for accessing persistent data in databases, using plain old Java objects (POJO) to represent the object model. Unlike Java Persistence API (JPA ... , and it is probably the most popular Java API for object databases today.
