No no no. Back to square one. Data independence means that the DBMS offers you commands to change the organization at the physical level, but when you issue these commands all your operations at the logical level, i.e., queries and updates, can remain unchanged even if they concern data for which the storage structure was changed.

So, to test if you understood this, can you tell me when this might be a useful feature? :-)
