Yes and no.

If you could get non-relational databases with same transactional
support, same tools, same vendor support etc..

And if all access to the database is OO based.

Then that would be obvious.

But the non-relational databases has not reached the same maturity level
(as a summary term for the above) as relational databases.

And it is common to have the same databases used by modern OO based
software also to be used by non-OO legacy software (like 20 year
old COBOL programs).

Oh - I have seen my share of that.

It should be mandatory for developers writing code using ORM to do some
testing with the logging of actual SQL statements executed turned on. It
reveals what is going on without having to know so much about the inside
of the ORM.

It seems as if very large parts of the Java, .NET and Ruby worlds
are able to make it work.
