body: <p>How to cache the query result in magento if I am creating some module.</p>
  
  <p>Basically I am creating one module for the announcement in which admin will add some announcement from the admin and it will be displayed on the front end(live website)</p>
  
  <p>Now if the information entered though the admin is not dynamic so I want to cache the information while modifying(add, edit delete )  and show in front end. it will save my database query time </p>
