Floyd Marinescu (editor of InfoQ.com) and Roberto V. Zicari
(editor of ODBMS.ORG's) have interviewed the following group of
leading persistence solution architects on their views on the
current State of the Union of object persistence with respect to Java:

-Ted Neward: Independent consultant, often blogging on ORM and
persistence topics

-Carl Rosenberger: lead architect of db4objects, open source

The questions at a glance:

Question 1: Do we still have an "impedance mismatch problem"?

Question 2: In terms of what you're seeing used in the industry,
how would you position the various options available for
persistence for new projects?

Question 3: What are in your opinion the pros and cons of these
existing solutions?

Question 4: Do you believe that Object Relational Mappers are a
suitable solution to the "object persistence" problem? If yes
why? If not, why?

Question 5: Do you believe that Relational Database systems are a
suitable solution to the "object persistence" problem? If yes
why? If not, why?

Question 6: Do you believe that Object Database systems are a
suitable solution to the "object persistence" problem? If yes
why? If not, why?

Question 7: What would you wish as a new research/development in
the area of Object Persistence in the next 12 months?

Question 8: 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?

Question 9: Any parting words about this topic?
