Meaning – A database administrator is one who is responsible for managing the working of a database system, at an individual or enterprise level. The main objective of a database administrator, is to ensure that the database runs efficiently. He/She makes use of specialised software to store and organise data within the database.

- System DBAs, who are responsible for the physical and technical aspects of a database, such as installing upgrades and patches to fix program bugs.
- Application DBAs, who support a database that has been designed for a specific application or a set of applications, such as customer-service software.
