This was a virtual panel organized by the editors of InfoQ.com (Floyd Marinescu) and ODBMS.org (Roberto V. Zicari). They asked a group of leading persistence solution architects their views on the current state of the union in persistence in the Java community. Our Chief Architect, Carl rosenberger was part of the panel.
Full list of panelists:
- Mike Keith: JPA 1.0 co-spec lead, architect, Oracle TopLink and Java persistence technologies

- Do you believe that Object Database systems are a suitable solution to the "object persistence" problem? If yes why? If not, why?

- If you were all powerful and could have influenced technology adoption in the last 10 years, what would today's typical project use as a persistence mechanism and why?
- Any parting words about this topic?
