Question

Quizplus · Accepted Answer

An external-level schema is a specific view designed for a particular user group or application. In this case, Mary Lamb's permissions and access to the accounting information system are defined within the company's external-level schema, which governs how certain data is presented to her and other sales reps. The other options (conceptual-level schema, data dictionary, and physical view) are more general database management concepts that are not directly related to Mary's access privileges.
