I am pretty new to OJB, too. This is one of the most frequent questions. If you get access to the mail archive (which is currently a bit difficult), you will find some discussions. To answer your question: we are using the ODMG API without the OJB internal tables and with the PB Query language. But we do consider to move to the JDO or PB API later. Therefore, we have wrapped the API by a thin access layer. > i don't know how use joins in API ODMG, its possible joins in > API ODMG?? Could you please explain what you mean by: "joins in the API"? Are you referring to the query language? In which way could you use joins? As to my understanding, both OQL and the PB query language are object oriented, so they should not offer a view onto tables, which is needed for formulating join queries explicitely. However, they certainly use joins "behind the scenes".
