Database Administration
Database Administration (DBA) is the practice of managing, maintaining, and securing database systems to ensure their availability, performance, and integrity. It involves tasks such as installation, configuration, backup and recovery, performance tuning, and user access management. DBAs work with various database management systems (DBMS) like Oracle, MySQL, or SQL Server to support organizational data needs.
Developers should learn database administration to optimize application performance, ensure data reliability, and handle scalability in production environments. It is crucial for roles involving data-intensive applications, system maintenance, or when working in DevOps teams where database management is part of the deployment pipeline. Use cases include managing high-traffic web services, financial systems requiring strict data integrity, or cloud-based applications with distributed databases.
