a,do i need to add "sychronized" to bookseat() function as i had lockmanager to implements lock/unlock? b,all the other function in remote interface which try to modify recodes should be add lock/unlock,such as in modify(){ lock(); localdb.modify unlock }? c,how many remote database object i need build for client?each client got one remote db object or just one for all remote clients?
a) If multiple clients call bookseat() method, then you need to synchronize it. b) lock() is something you need to outside of modify(). No need to add lock() in the modify() method c) What do you mean by remote db object? I suggest you have a unique remote DataRemote instance. DataRemote class implements the interface which is also implemented by the Data class.
