Dear All,
I wants to develop one application in which i wants to data communication between server and client where client should be POS.I mean there are POS and i wants to update data to server from POS.
· Client should have periodic transfer for data
· Either it should be connected to web service permanently or connect on periodic basis
· Should have option to validate if internet is connected
· If no internet than should attempt 3 times to connect to web service than try at scheduled time
· Client application should have option of read text file, sql server/access and xml file.
· Configuration should be done using .ini or config file
· During data transfer if internet disconnected(or any other reason) than should revert (revoke the process) and bookmark the data for future transaction
· I don't know if we can bulk transfer the data if yes than bulk should be the best option.
