What Does a Database Administrator Actually Do?

Database administrators manage, optimise, and secure the databases that organisations rely on — everything from routine backups and performance tuning to disaster recovery planning and access control. They work in finance, healthcare, retail, government, and tech, reporting to a head of infrastructure or IT director. A typical week involves monitoring query performance, running index maintenance, supporting developers with schema changes, and responding to production incidents. At larger organisations, DBAs may specialise in a single platform like Oracle or SQL Server; at smaller companies, they often manage several simultaneously.

What Recruiters Look For

DBA CVs must show your database platform expertise, the scale of environments managed, and uptime achievements. Include certifications (OCP, MCSA), number of databases managed, and high-availability architecture experience.

Key Skills to Include

SQL Server, PostgreSQL, Oracle, performance tuning, high availability (Always On, Data Guard), disaster recovery, cloud databases (RDS, Aurora), and automation (PowerShell, Ansible).

Common Mistakes

Not quantifying the scale of your environment. State the number of databases, total data volume managed, and your uptime SLA. Migration experience (on-prem to cloud) is increasingly valuable.

Formatting Tips

One to two pages. Lead with certifications and database platform experience. Include an Environment Summary showing database counts, platforms, and sizes managed.

Top 5 Interview QuestionsDatabase Administrator

1Walk me through how you would investigate and resolve a sudden drop in database query performance.
Cover execution plans, missing indexes, locking and blocking, hardware resource contention, and recent schema or data changes. Systematic diagnosis matters here.
2How do you approach database backup and recovery planning for a business-critical system?
Discuss RPO and RTO targets, full vs. incremental backup strategies, off-site storage, and regular restore testing. Many candidates forget the restore testing part.
3Describe a time a database outage affected production. What did you do?
Be honest about what happened, focus on your immediate response and communication, and explain what you changed to prevent recurrence.
4How do you manage access control and security for a database containing sensitive customer data?
Reference principle of least privilege, role-based access, auditing, encryption at rest and in transit. Show GDPR or equivalent compliance awareness.
5Tell me about a migration or upgrade project you've managed. What went wrong?
What went wrong is the important part — it shows maturity and planning ability. Explain the risk you underestimated and how you recovered.

How to Tailor Your CV

Oracle, Microsoft, Amazon Web Services, NHS Digital, and large financial institutions like HSBC and JPMorgan all hire database administrators. Oracle and AWS cloud DBA roles require strong skills in Oracle DB or AWS RDS and Aurora — cloud certifications like AWS Database Specialty add real value. Microsoft shops want SQL Server expertise, SSIS, and ideally Azure SQL experience. Healthcare organisations like NHS Digital prioritise data security, compliance, and HL7/FHIR integration knowledge. Financial sector roles care deeply about high-availability architecture and disaster recovery.
