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.
