# maintain database performance — Database Administrator

As a Database Administrator, 'maintaining database performance' isn’t about *making* things fast initially – it’s the ongoing work to *keep* them that way under real-world load. Daily tasks revolve around monitoring key metrics (CPU usage, I/O wait times, buffer cache hit ratios) using tools like SQL Server Management Studio, Oracle Enterprise Manager, or open-source options like pgAdmin and Prometheus + Grafana. You'll be constantly analyzing query performance – identifying slow-running queries with execution plans, suggesting index improvements to developers, and sometimes rewriting queries yourself. It also means proactively addressing things *before* they become problems; scheduled jobs for statistics updates are crucial, as is regular review of auto-growth settings.
