Hey,
I just need a notification on apex page when the entry inserted into the database weather it is using back end or weather it is from apex page.

And I answered along those lines.
Apex does not know if a database value has changed, unless it goes back to the database and actually queries that data.
If you want the database to be able to "send a signal" to an Apex application that the data has changed, then see the original answer.
Otherwise, your Apex app would need to poll the database intermittently.
