First, Many Congrats And you got a good score too.
I have a couple of questions, if you can answer them that would be great.
1. Can you give a high level overview of your locking approach?
2. Can you suggest where you might have lost points in General Considerations and Documentation section?
Thanks.

Thank you.
1. About the lock, I hae two level lock.
The first level is to lock&unlock the record. I create a unique instance of
class dealing with lock record. This class has a HashMap,which holds an Object. Both lock and unlock methods synchronize the HashMap object.
The second is the Database file
Database file read and write thread is managed by synchronizing the handle which read&write file.
2. The lost
<1> My native language is nont english, and I think these will be the main reason I can do well as other.
<2> I change my structure in the middle, so some my structure may not very clear. At the same time, some of the detail I do not pay enough attention. It is a good idea for you to have a clear structure before you start your work.
Hope all of these will give you some help.
