Show answer & explanation
Correct answer: C
Step 1: Understand that data models are used to abstract data from physical storage, allowing users to interact with data at a conceptual level. This supports data abstraction. Step 2: A self-describing database system stores metadata about its structure, enabling it to manage data independently. This is a key feature of the database approach. Step 3: The database approach supports data independence, meaning changes in data storage do not affect programs. This allows flexibility in database design. Step 4: Multiple views allow different users to see data in ways that suit their needs, which is a supported feature in database systems.
