Data modelling in information systems is primarily associated with which activity?

• A. It models the relationships between data elements
• B. It creates dashboards for decision makers
• C. It configures hardware for ETL
• D. It involves analysis of business data

Answer: (D)

Data modelling in information systems focuses on organizing data elements and their relationships so information can be stored consistently and analyzed reliably. By defining entities, attributes, keys, and constraints, it creates a structured representation of the business data that supports accurate reporting and decision making. Because the aim is to enable meaningful analysis of business data, the activity most closely associated is analyzing business data to derive insights and inform decisions. Dashboards are outputs that present data after the model is in place, configuring hardware for ETL is a technical setup, and while modelling involves understanding how data relates, its primary purpose is to enable analysis of business data.
