QUESTION POSED ON: 10 December 2007
I have a number of tool vending machines all connected to a SQL Server database to record stock levels and transactions. One of these vending machines is connecting to the SQL Server database through an ADSL link and is constantly experiencing loss of connection between it and the database.

What I've been thinking is to host a copy of the database on the vending machine using the ADSL link and then having the two databases do a two-way sync every couple of hours. My problem is due to my lack of knowledge and experience with SQL Server databases.

The idea of having a local database that syncs when scheduled is to minimize the WAN connectivity issues. What's the best way to proceed?
