Hi All
I have some doubts with this assignment requirement specification.
In the spec, they mentioned the program must be able to work in a non-
network mode. That means database and user interface run in the same
Does the non-network mode means single user mode, so the program can
directly access the daba object?
If not, the non-network mode is still a multi-user mode, how the
multiple processes share the same VM without networking and sockets
Any helps are appreciated.

Non-networked mode means single-user mode. There is no way multiple JVMs can safely operate on the same file (alright, not true, you could do something with lock files, but that's way outside the assignment's scope).
