Which level of access does an Administrator have in a database?

An Administrator in a database typically has full control over the database system, which includes the ability to perform a variety of critical tasks. This encompasses schema modifications, meaning they can add, alter, or delete tables, views, and other structural elements within the database. Additionally, Administrators are empowered to manage user permissions, create and delete user accounts, and oversee database security protocols. This comprehensive access ensures that they can effectively manage the database environment and respond to changing requirements.

The other choices imply significantly limited access levels that do not align with the responsibilities and capabilities typically expected from an Administrator role. Options highlighting restricted access or limited ability to only perform certain actions would not adequately allow an Administrator to fully maintain and optimize the database system.
