What Is the Process of Database Administration?

Database administration is the process of organizing, storing, and maintaining data in a database. It includes tasks such as designing the database, setting up user accounts, backing up data, and ensuring the database is secure.

Database administrators (DBAs) use various tools to manage databases, including graphical user interface (GUI), command-line, and web-based tools. They may also use scripts or programs to automate tasks.
