Answer 1

Correct answer:
To show how to set up a database using a specific database management system.

A physical data model defines the actual implementation details for a particular DBMS — tables, columns, data types, indexes, constraints, storage and performance considerations. A high-level view is the conceptual/logical model; user interfaces and software updates are unrelated.
