Orient is a true ODBMS (Object Data Base Management System) written in C++. It can store and retrieve objects to database without any conversion. With Orient you don't write a line of code to persist objects. The application will be much faster and the development process strongly reduced: from 50% to 80% less code. Orient supports: - Java using Sun JDO technology - C++ using ODMG 3.0 worldwide standard - SQL-92 subset with extension for objects to query the database - XML using XMLObjects Orient is not supported anymore.
