# database management systems — Database Administrator

For a Database Administrator (DBA), 'Database Management Systems' isn’t just *knowing* Oracle, MySQL, or SQL Server exists – it's breathing them daily. It means being able to install, configure, and patch these systems across various environments (dev, test, production). A huge chunk of the job is performance tuning: analyzing query execution plans, identifying bottlenecks using tools like Performance Monitor (Windows) or `top`/`iostat` (Linux), and adjusting database parameters to optimize speed and resource usage. You'll also be deeply involved in backup & recovery strategies – designing them, testing restores regularly, and being the first responder when data loss *does* happen.
