Step-by-step explanation:
The career in which a person manages, secures, upgrades, and backs up databases is known as a Database Administrator (DBA). In this role, the DBA ensures that databases are running efficiently and are guarded against unauthorized access or loss of data. They also oversee the implementation of new databases and the maintenance of existing systems. Furthermore, it's part of their job to regularly back up data to prevent data loss in the event of a system failure, and to recover data as needed.
A Database Administrator is responsible for database tuning and performance monitoring to maximize the speed and efficiency of database queries. They also work closely with IT project managers, database programmers, and multimedia programmers to ensure that applications work properly with databases. As technology grows and changes, the DBA must keep up-to-date with the latest database versions and features.
