Fragmentation transparency states that the performance of functions such as adding sites, changing versions of DBMSs, creating backups, and modifying hardware should not require planned shutdowns of the entire distributed database

D. Fragmentation transparency

Explanation:

In DBMS update normally happens with proper backup taken and shutdown the database server and well planned. But in distributed database during update avoided shut down process. Moreover data base is distributed mostly fragment transparency is used.

Fragmentation transparency means data are stored in distributed manner data is available any time and it is completely handled by system. So DBMS update process is done without making necessary backup and shutdown process, planning on DBMS update can be any course of time.

In distributed database data model is stored virtue of internal details where only system can access.
