Day-to-day operating brief
What Database Administrator (DBA) work looks like in practice
A Database Administrator maintains database platforms, performance, access, backup and recovery for systems holding operational and personal data. The role may execute powerful production changes, making separation of duties, audit trails and tested rollback essential. Terms should identify platforms, environments, privileged credentials, maintenance windows, on-call cover, capacity, encryption, vendor support and incident authority. Recovery evidence should record the restored point, data loss window and application validation, not simply that a backup file opened. A database can restore cleanly while remaining inconsistent with linked queues, files or services. Capacity planning should consider growth, maintenance workspace, replicas and recovery operations together. A database with comfortable daily utilisation may still be unable to rebuild an index or restore alongside the live service. Failover procedures should identify application reconnection, replication lag and authority to return to the original primary, not merely the database command that promotes a replica.
