Object databases based on persistent programming acquired a niche in application areas such as engineering and spatial databases, telecommunications, and scientific areas such as high energy physics [13] and molecular biology. [14] Another group of object databases focuses on embedded use in devices, packaged software, and real-time systems.
Embedded database supporting efficient, distributed management of C++ and Java objects. Avoids the complexities and limitations of ORM products such as Hibernate by storing objects directly with their relationships intact.

ObjectDB is an object database for Java. It can be used in client-server mode and in embedded (in process) mode. Unlike other object databases, ObjectDB does not provide its own proprietary API. Accordingly, working with ObjectDB requires using one of the two standard Java APIs: JPA or JDO.
