As well as standalone Java applications, JDO can be used to build J2EE, RMI, or CORBA applications also. In particular, JDO has been specifically designed to work in conjunction with J2EE. Essentially, wherever a Java application can directly use JDBC today, JDO likewise could be used.
In many ways, JDO offers a programming model and approach to object persistence similar to Container Manager Persistence (CMP) from the Enterprise JavaBeans (EJB) specification.
