this article, join fetch seems to be the right choice. What about ObjectDb ? The implementation is totally different. Is an "All eager strategy" more efficient that many join fetch ( cartesian product + distinct ... all strategy" Or "Fetch Join strategy" for ObjectDb ? Regards, Xirt xirt Sylvain Is an "All eager
