A Database Administrator (DBA) manages, monitors, and maintains databases for optimal performance and security. They design and develop database strategies, system monitoring tools, and data management techniques. They also ensure data consistency, integrity, and availability. They oversee backup, recovery, and performance tuning, troubleshoot issues, and implement database updates or migrations. DBAs often liaise with IT project managers and database programmers to create and protect databases that meet user requirements. Moreover, they ensure compliance with the legal requirements of data security, privacy, and confidentiality. They play a crucial role in business continuity planning, data disaster management, and data storage.
