your explanation (in Modifying vs inheritance )is really very deep and clear.
I was about to pack my project but now after reading your explanation I got stuck.

Originally posted by Peter den Haan:
"The RemoteData class is a subclass of Data responsible for providing access to a single local database file, comprising reading, writing and searching facilities, managing record and database locks for remote mode operation, and generating client IDs for remote clients. It is a Remote object to be exposed using RMI. The lock methods inherited from Data that do not take a client ID should not be used."
Exaclty you mean to say RemoteData class(remote object) will extend Data class ? if that is true then my design is really wrong. u saved me. pl. comment on my design :
Data class implements dataInterface
RemoteData class extends UnicastRemoteObject, implements DataInterface
I have literally replicated Data class methods in Remotedata class(cut-paste), except RemoteData class is throwing RemoteException and implementing lock and unlock methods.
Is this correct or not proper OO design. Can u pl. comment (and guide)?
