As far as I can see, the update and create method in the DB interface are never used. Do I have to fill the implementation with working code ?
What if the room was already booked by another client inbetween ?
Do I have to display a message to the user, that his selection was already booked while he made his decision ?

In this case it should be sufficient to "synchronize" the update method, isn't it.
Do I miss something ???

By the way: My apologize about my display name, I wasn't aware of that. I changed it now from M. Groening to Linus Friedrich.

Is it exceptable to change the interface by declaring exceptions?
i.e.
This
public String [] read(int recNo) throws RecordNotFoundException;
to this
public String [] read(int recNo) throws RecordNotFoundException, RemoteException;

I don't think this change is ok. So I write a new Interface for
client ,for RMI server.
For the DB class , I just implement it to Data class.
Maybe the request just want some olg system can access the new application through the interface,So you should not change this DB interface.
