Which statement correctly identifies the Physical model?

• A. Physical model
• B. Data Manipulation
• C. Conceptual model
• D. Logical model

Answer: (A)

The key idea here is the different levels of data modeling. The physical model is about how data is actually stored and implemented in a specific database system. It covers details like table structures, column data types, indexes, partitions, storage parameters, and other DBMS-specific choices that affect performance and storage.

That’s why this option is correct: it directly describes storage and implementation aspects of the database. The other ideas don’t fit as a model focus. Data manipulation refers to the operations you perform on data (insert, update, delete, query). The conceptual model is a high-level view of what data exists and how it relates, without technical storage details. The logical model defines the structure of data (tables, keys, relationships) in a way that’s independent of a particular DBMS, without getting into physical storage specifics.
