Yes. But I meant a distributed system. Object persistence alone is not
enough for a great number of applications. Translated into DB terms: a
distributed system is when you have stored procedures. Just persistence
means that you read object(s), process them locally and then store back.

Why should it be any problem? Considering OO as an advanced ADT, I see no
clear alternative. If you mean that established OO religion, well, that is
not a technical issue.
