ObjectDB requires Java 8 or later. As a pure Java application , ObjectDB should be able to run on any platform that supports the Java Standard Edition. Either the Java Development Kit (JDK) or the Java Runtime Environment (JRE) can be used. A version of ObjectDB for .NET is currently under development.

The following JPA annotations are in use to integrate JPA into a Java EE application and are managed by the Java EE container:

JPA Entity classes are user defined classes whose instances can be stored in a database. To store data in an ObjectDB database using JPA you have to define entity classes that represent your application data object model. This chapter explains how to define and use entity classes.  This chapter contains the following sections:
