Store in local database when remote SQL Server unavailable and then sync when connected

Question

I am developing a C# Windows Forms app for event management. There will be 15 gates with RFID readers. These readers will read the UID and query the database to check if it is unique entry for that day.

Now if for some reason, SQL Server is not available, I want the app to store the data in a local database and sync as soon as the connectivity is restored.

Any idea on how should I do it?

Thanks

您可以使用SQL Server复制，并在每个设备上使用数据库的本地副本安装SQL Server Express。
