I understand everything up to "In our application ..."

I don't understand how it can be efficient (server CPU/bandwidth/etc)
for the client to constantly poll the DB to see if there is anything
there yet... Also, if you poll less frequantly, then your phone is
already ringing before the data arrives which is also not so great...
