1. You use the REFRESH META tag so that the page refreshes on its own after a spefic period of time and get the fresh data.

ie, like

<META http-equiv="REFRESH" content="65">

2. User Server Push in which the connection b/w the server & the client is not closed and kept alive.

I don't want to refresh the page after x seconds, only when the database is modified.Tell me more about the second method, please.
