Frequently Asked Questions

Which metrics work best on a DBA CV?

Availability (uptime) percentage, improvement in query response time, the data volume you manage and your RPO/RTO targets are the most effective. They show the employer your reliability directly.

Is knowing only one database engine enough?

Knowing one engine (for example PostgreSQL) in depth is enough for most roles, but a second engine plus replication/backup experience strengthens your application. Solid SQL and optimisation are expected everywhere.
