I've always felt that begs the question, by assuming that a mismatch is somehow fundamental, rather than an implementation artifact. Just as real RDBMSes don't strictly adhere to the formal math relational model, object-oriented languages vary in their, for lack of a better word, orientation. Looked at another way, what about a relational-object model instead? Making a useful one for MySQL doesn't seem as plausible, given its chronic feature absence.
