asp.net - fetch data from a database server to local application continuously -

-

i have application collects information customers using asp application in website. application writes information database (sql server) in remote server (web server). want information in database updated local pc in real time i.e. data added web server db same should downloaded local server (offline server). summarize want push notification of data changes web server local pc.

there numerous ways accomplish - choose depends on constraints of particular situation. simplest have local application poll server @ regular intervals. crude has advantage work without modification router/firewall settings. alternatively write code on asp application send message local application when change occurs. true push, fail without port forwarding on router; if can configure router, code should straightforward enough. question vague answer here - replies saying 'ok , bit stuck with?', 'what have tried?' etc
