Hi All,
I just started to work on this assignment. The database provided is a file. So, doesn't the file need to be locked every time some thing is written to it? I don't see where in the Data class it keeps track of record objects. I am confused about how locking an individual record would help when the object that is holding the data that needs to be protected is in a file?
Thanks in advance for any help.
Aruna.
