Designing a OO database model

["Jon Finanger" <Jon.Finanger@q-free.com>]

Since OODB is pretty new, some questions arise regarding to the design of OO
database model:
Since Ozone uses RMI one need to work with interfaces (to create the
proxies). Am i right when i say that if you're going to make an inheritance
hierarchy like this: Emplyee inherits from Person
you have to do it using interface inheritance?

or do i just implement a PersonContainer interface and uses a
setPerson(Person p) method in that to store a serializable Employee object
or some other Person?

or have i completely misunderstood :)
