I made application (using .NET) to transfer data using PDA via GPRS and
then upload data to database server. The data not update old data but make
new insert new data to database server.

If we use USB to synchronize data from PDA to database server, we can use merge replication. But i still confused how to synchronize data, if we transfer data from PDA via GPRS, then insert to database server.
