Question

Quizplus · Accepted Answer

Cornelia's permissions are specific to her role as a sales representative, which means that her access is controlled by a subschema within the company's overall database management system. A subschema defines a subset of the overall schema that is tailored to the needs of a specific group or individual within an organization. The other options (conceptual-level schema, data dictionary, physical view) do not accurately describe Cornelia's permissions within the system.
