I´ve already implemented the DBAccess interface provided by Sun. All methods are done.
My GUI just need to book and locate (by name and location) records. So the clients doesn't need all the methods that I've implemented in DBAccess.
Does my Remote interface need to have all the methods that DBAccess has or can it have just the book and locate method?
This is a very good question. I chose to put all methods of the interface that was provided to me in this interface too, you know... because today, not all methods are necessary, but might be one day...
