all client will read/modified the same database file(.db) if there was a changed in databasefile(.db) then a client who is reading the database file will see the change(refresh by itself in the jtable).
so i don;t do anything about loading all records into d.struc(e.g linkedlist), read and changed/update will happen directly on the databse file(.db) is it correct?

All clients read/write to/from the same db file. It's your choice if you want to implementing record cache-ing or not.
IO has a large performance overhead so is a prefered choice by some, however this is not required to pass.
Either way, it a good talking point you should consider in the written exam. [ December 15, 2004: Message edited by: James Clinton ]
