What Is A Database Administrator (DBA)?
A database administrator manages the databases a company’s applications depend on, keeping them fast, available, and secure. That means tuning performance, running backups and recovery plans, controlling access, planning capacity, and handling upgrades and migrations so engineering teams can rely on the data layer without worrying about it.

What A Database Administrator Actually Does

- 02 · Backups & RecoverySets up and tests backup and disaster-recovery procedures so data can be restored when something fails
- 03 · SecurityManages access controls, encryption, and patching to keep databases secure and compliant

- 05 · CollaborationWorks with developers and data teams on schema changes, query reviews, and data access needs
Database Administrator Vs. Similar Roles
| Role | Main focus | Primary metric |
|---|---|---|
| Database Administrator | Keeping databases performant, available, and secure | Uptime, query performance |
| Data Engineer | Building the pipelines that move and transform data | Pipeline reliability, data quality |
| Backend Developer | Building the APIs and server-side logic that use the database | Feature delivery, API reliability |
| Site Reliability Engineer | Keeping production systems reliable as they scale | Uptime, incident response time |
At smaller companies, backend developers or DevOps engineers often cover DBA duties part-time. Split the role out once data volume, uptime requirements, or compliance needs justify dedicated ownership.

Frequently Asked Questions
A database administrator keeps databases performant, available, and secure, and is measured on uptime and query performance. A data engineer builds the pipelines and systems that move and transform data across an organization, and is measured on pipeline reliability and data quality. At smaller companies, one hire sometimes covers both.
A backend developer builds the APIs and server-side logic that read from and write to the database, and is measured on feature delivery and API reliability. A database administrator owns the database itself: its performance, backups, security, and upgrades. Many small teams have developers cover DBA work until the data layer needs dedicated ownership.
US database administrators average around $102,260 a year. Database administrators in Latin America with 6 or more years of experience average around $59,500 a year, about 42% less, saving roughly $42,800 a year per hire.
Most searches run 21 days from kickoff to a signed offer, with 3 to 5 candidate profiles delivered in the first 10 days.
Often yes. Managed services like Amazon RDS or Azure SQL handle much of the patching and backup infrastructure, but someone still needs to own query performance, schema design, access control, and recovery testing. Smaller teams sometimes cover this part-time with a backend developer or DevOps engineer.
