database - javascript: to make backend db changes is reflected to browser instantly, is it possible? -

here problem. have hardware scanner connecting windows computer. when scan item windows computer price/information item. insert price database through windows program/c# program.

i have web application, has access same database c# program . web application should open @ time when scanning. changes in db reflected web browser right @ time when scan.

is related javascript technology(or other technology)? possible?

thanks

if web app, running on web server has access database , can notified of changes, use http persistent (aka keep-alive) connection 'push' updates down pipe browser js pick them up
