Companies and organizations heavily rely on databases to manage their daily operations and make informed decisions.
Learning to manage databases has become an essential skill for many information technology professionals.
A database administrator (DBA) is responsible for maintaining the availability, reliability, and performance of databases, ensuring that data is accessible to authorized users and protected against unauthorized access.
In addition to job opportunities, learning to manage databases fosters the development of analytical and problem-solving skills.
These skills are transferable to other aspects of information technology and can enhance a professional’s ability to tackle technical and business challenges.
