Prior knowledge or experience in database programming (SQL, JDBC, ORM, JPA, etc.) is not required, but some background in using the Java language is essential.
Can I use ObjectDB with languages other than Java?
ObjectDB can be used by Java Virtual Machine (JVM) languages, such as Java, Groovy and Scala. It can also be used with other languages, such as Phyton, Ruby and PHP, but currently only with their JVM implementations (e.g. Jython for Phyton, JRuby for Ruby and Quercus for PHP). A version of ObjectDB for .NET is currently under development and future support for other languages (including full Phyton, PHP and Ruby support) is planned.
