Question

Quizplus · Accepted Answer

The permissions granted to the sales reps define an external-level schema in the company's database management system. This schema defines how the data is viewed by the end-user, in this case, the sales reps. They have access to a specific subset of the data and the operations they can perform on it. The other options are not a good fit because conceptual-level schema refers to the overall design of the database, data dictionary is a repository of metadata about the database, and a physical view would define how the data is physically stored on disk.
