How can I make the real-time synchronization between main server and target server?

I have occurred in a serious problem, I had inserted some data into table from main server to local server through SSIS ETL technique. All is perfect till scheduling. But the main problem is, if in the main server table if we delete or update a row against any id, that data won't delete or update at the local server. How can we solve this problem? I mean what happens at the main server, same thing should be happened at the local server after scheduling occurs at the local server. How can I achieve it? Please apologies for the grammatical errors and I'm newbie here
