Hi,
Thank you for reply.
I am trying to develop an offline POS system. This app does not connect to backend directly. It is designed to able to keep "doing business" if backend server down.
My "service" should keep checking for changes of my log table. If any, the program should update the changes to backend database.
Any ideas?
Thank you

I am not the worst man in this world either.
I just as same as all of you.
I still need to learn from my mistakes...
