Which term is used for modelling the structure of data?

• A. Fidelity
• B. Digital human
• C. Conceptual modelling
• D. Data Modelling

Answer: (D)

Modelling the structure of data means defining how data is organized—what data items exist, what attributes they have, how those items relate to one another, and the rules that govern them. This creates a data model that acts as a blueprint for storing and retrieving information in databases and information systems, ensuring data is consistent and usable. The term for this overall activity is data modelling. Conceptual modelling is related and focuses on high-level structure and meaning, but data modelling covers the broader design for storage and use. Fidelity is about accuracy, not the act of designing data structures, and a digital human is unrelated to modelling data structure.
