Final answer:
The given statement is true. DBMS administrative functions include backing up database data, adding structures to improve performance, and removing unwanted or unnecessary data.
Step-by-step explanation:
DBMS (Database Management System) administrative functions include various tasks such as backing up database data, adding structures to improve performance, and removing unwanted or unnecessary data. These administrative functions are essential for maintaining the integrity and smooth operation of a database.
For example, backing up database data ensures that a copy of the data is available in case of system failures or data loss. Adding structures, such as indexes, can enhance the performance of database applications by allowing faster access to specific data. Removing unwanted or unneeded data helps to optimize storage space and improve query performance.
Database management system (DBMS) administrators are responsible for the maintenance, backups, optimization, and security of the databases. Backup tasks involve creating copies of data that can be restored in case of data loss. Performance in database applications can be improved by adding structures such as indexes, which facilitate faster retrieval of data. Data pruning, which includes removing obsolete or unnecessary information, is also a critical part of DBMS administration to ensure efficient database performance and to conserve storage space.
