Database Administrator Sample Job Descriptions

What Does a Database Administrator Do?

A database administrator (DBA) manages and maintains the systems that store and organize an organization’s data. They ensure that databases run efficiently, securely, and remain accessible to authorized users at all times. From configuring and upgrading systems to managing permissions and availability, DBAs are responsible for the health and reliability of mission-critical data environments.

Beyond routine maintenance, DBAs play a key role in supporting business operations through performance tuning, query optimization, and data recovery planning. They work closely with software developers, analysts, and IT teams to maintain data integrity, optimize resource usage, and enforce security protocols. Whether managing on-premises systems or cloud-based platforms, the DBA ensures databases scale with business needs and remain resilient against threats and failures.
