The difference between the two connection modes ?

[Morten Nielsen]

Is it correct, talking about the two ways the assignment is telling me to inplement the use of the server, that the Network modes must be threadsafe and the local-same-vm-mode doesn't because it is a single-user connection, or am I wrong ??

[Mark Spritzler]

Local mode does not use the server at all, no RMI in local mode. Think of it as a stand-alone program.

So when I run in the localmode, the connection to the DB doesn't have to be threadsafe, correct ??

Well the Data class itself has Synchonized in them, but it won't have any effect to one user.

How come this same Data class synchronised methods will be used both for local and network connection? there's no point in having synchronised methods in local mode. right?
I feel that local mode also has to be thread-safe, bcos Data class has synchronised methods.
So in my design, i made sure that irrespective of method of connection, the locking mechanism is thread safe.
Is this fine, and how do i document my views in design.txt?
thanks,

Well in local mode you will not do any locking, since there is no chance that there is any other user locking the record. Because there are no other users.

[Yes, i understand that, but why then are we using synchronised methods of Data Class,
in local mode?

Hey Mark, can u please help...

Hey.I am a new one .
I think: There is only one user to call the method in the Data class .So Synchonized it or not has no different! I think!
