Congratulation !
what a great score . You must be prof. developer.
one question if u dont mind ?
did u wrote whole lock and unlock methods in Data class also or only defination(as Data class is used only for local mode)?
Or u kept complete lock & unlock methods in Both classes (Data and RemoteData)?

I implemented a lock manager which took care of managing the locking mechanism. This allowed for encapsulation. The Data class unlock and lock methods use the lock manager since the Data class is mainly used for non-remote database services. The RemoteData class basically provides the remote database services so the unlock and lock methods implement sending the request over to the server. I then used a factory so that a client can just ask the factory for either a remote or non-remote database object. Using an interface provides the polymorphic behavior so the client can just invoke the lock or unlock method on the database object hiding the remote and non-remote implementations.
Hope that helps!
