I expected an apples-to-oranges comparison.

So, is the class hierarchy or object model itself stored in the oodb? If so, does it use a representation such that, a reader of the oodb with full knowledge of Xdb, but no knowledge of the application's objects be able to bootstrap
its own way to making full use of the objects stored in the oodb?
