Note that ODB has a mechanism for changing the place (as in the header)
where it "thinks" a class is defined so it should be possible to compile
the "mapping" file and get a sensible result if you that's what you want.
This is described in more detail in the "Custom C++ to Database Type
Mapping" blog post, the "Composite Value Types" section (the post uses
it to handle a composite value type but it works equally well for objects):
