distributed DBMS

Give brief answers to the following questions:

  1. Why is giving database objects unique names more complicated in a distributed DBMS?
  2. Describe a catalog organization that permits any replica (of an entire relation or a fragment) to be given a unique name and that provides the naming infrastructure required for ensuring distributed data independence.
  3. If information from remote catalogs is cached at other sites, what happens if the cached information becomes outdated? How can this condition be detected and resolved?
