    Hi Guru,

    please take a look at the documentation which contains a lot of information about Java Persistence ( > Developing Business Logic > Java Persistence).

    To give you a first hint: SQLJ belongs to the area of relational persistence and you have to write SQL statements into your code whereas JDO is object-relational and offers more transparency for the developer.
