I’m writing an app to assign referees to matches in a competition. 2 guys, who are 2 hours drive apart, need to modify data, sometimes simultaneously. This is new for me but assume the program will have to keep checking the server for new data? If so, what sort of interval for checking the server is best? Or is there a method to ‘push’ data down? Is websockets what is needed here?
The other way I was thinking is while 1 user is editing the other users becomes read only. That any good?
Thanks in advance.
