Alert on DB insert and update

Is there a way where can the App dispaly alert (or change LSV value) once a new record inserted into DB or updated?

What I am trying to ahcieve is for example in camera tutorial (http://devcenter.appery.io/tutorials/...), I want when I change some label value (from backend DB), a badge will appear. Given that there are multiple records and more than one might be updated, a different value is needed for each record (dynamic number of records) so that new or updated records will be flagged (e.g. listitem will painted in different color). But eventually only two types of badges will apear, one for update and one for insert.

Is that possible? and do I need to use specific service for this?

Many thanks
