A Java string isn't precisely the same thing as a varchar(255), for example. Nor is an ArrayList (ordered) the same thing as a set of rows (unordered). Mapping between these slightly different sets of concepts usually works well enough, but it's an additional piece of disjointedness.

But it's unavoidable.

At some point you have to do that translation. And I would rather leave that up to the ORM where it fundamental to what they do then reimplement it.
