SQL Server Express database replication/synchronization

Situation: Hi, I'm coding using Lightswitch (C#) and am thinking of deploying to multiple sites the same application and database.

The databases need to be synchronized/replicated to each other so each would have a merged database. However connectivity between the sites is not going to be 100%, so the synchronization/replication would be done whenever the connection is possible.

Question:

Would it be possible to accomplish this through SQL Server Express? If not, what would be the best way to accomplish this by code? Thanks!

SQL Express doesn't support replication (except as a subscriber, as Davide pointed out). I think your best bet would probably be a windows service that keeps track of table names and the most recent timestamp processed.

Integration Services is also an option if you have a server to run it on.

Do you need data to be moving one-way or both ways?
