Hi. I was creating an enrollment system for my Thesis, and my adviser told me that I must have a Code in my program that Synchronize database from client and server so that if the terminal connection is "Up" the data will go to the server and if the connection is "Down" the data will go to the installed server on the the local machine. and every 20 mins or 30 mins will sync the database. can somebody help me. Any Idea how to do this Sync thing. thank you. :) have a nice day.
