We have a small branch app that stores some data in a SQL Express Database.
We want to have an almost real time copy of this table in our headquarters, were we have SQL Enterprise 2014. I say almost, because it doesn't matter if there is a 5 minute delay or something like that.
The main thing is that it's able to synchronise after a network disconnection between branch and headquarter.
Any solution that does not requiere licensing costs for the branch office?
