In RD how will u fetch a case and save it in it not using data page so that instead of making call to db again and again it uses RD

hi @RameshSangili so if we are using an activity as well still the DB will be hit right,but the scenario that i was asked was the db should not be hit multiple times how to configure RD in such a way that it caches the data within it instead of again and again calling the Db to fetch the data without using Data page.
