Database management systems are essential for businesses and companies. They provide centralized access to data for various end users in an organization. Being an integral part of any business, it means that if its performance is slow or affected in any way, the day-to-day activities of the company or organization are greatly affected. This calls for the need for such systems to run smoothly throughout as their sudden failure can lead to losses and other inconveniences. A database administrator is pictured authorizing access to the databases. This means that for any database management system to work optimally, it is necessary to have a database administrator on the ground to keep it in mind.
It also means that there are no unauthorized personnel or users who can access the database without first going through the DBA. The DBAs are responsible for ensuring that the entire performance management database plays the role for which it is designed and efficient. In this guide, we will look at various roles played by the various database management system administrators responsible for database systems.
