Database Administrator
Keeps an organization's databases running, secure, and performant.
A database administrator (DBA) manages the systems that store an organization's data, making sure they're available, fast, backed up, and secure. Day-to-day work includes monitoring database performance, tuning queries that are running slowly, managing backups and recovery plans, and controlling who has access to what data.
DBAs often get pulled in during incidents (like a slow application or a failed backup) and spend time planning ahead, capacity planning, security audits, and migrations to new systems, to prevent those incidents in the first place.
