Not AFAIK. It's one of the problems mapping between the two. Object
oriented design is based upon software engineering principles,
relational databases are based upon mathematics principles.

This is not to say that one is more or less valid than the other, less
proven (though I wouldn't know how to prove a software principle...),
or less tested, just that they originated in different places and
hence their communication can be a bitch.

For example,

If you have time, I recommend running around agile data and reading
the essays. Lots of good stuff on there.
