Object cache instances (is this approach right)

Hi,<br />
<br />
  If we have to avoid hitting the database for every request sent from
frontend(UI) to the service , can we use Object Cache instance approach to cache
the response data for a given interval of time.So we can see if the reponse data
is present in the cachce instance else so and hit the data base.Is this approach
Ok?<br />
<br />
