What does database administration include?

Database administration is managing, configuring, and maintaining a database system so it stays reliable, fast, and secure.

#The main areas

It usually covers several areas:

1. Installing and configuring the DBMS. Installing the database server (e.g. MySQL, PostgreSQL, SQL Server) and setting its runtime parameters.
2. Creating and managing users. Granting access rights and protecting against unauthorized use.
3. Backup and recovery. Setting up backups so data can be restored after a failure or mistake.
4. Monitoring and optimization. Tracking performance, finding "heavy" queries, tuning indexes.
5. Updates and maintenance. Installing DBMS updates, fixing bugs, controlling data volume and logs.
6. Ensuring security. Protecting passwords, encryption, auditing user actions.

Summary: administration is everything needed to keep the database running stably, quickly, and safely.
