Which of the following is NOT a major DSS component?

• A. Data management: select and handle appropriate data
• B. Dialog management: facilitate user interface to the DSS
• C. Network management
• D. Model management: apply the appropriate model

Answer: (C)

In a DSS, the parts that directly support making and presenting decisions are data management, model management, and dialog management. Data management organizes and provides the data the system uses for analysis. Model management stores and applies the analytical models, simulations, or optimization techniques that turn data into insights. Dialog management handles the user interface and interaction flow, letting you set parameters, run analyses, and view results.

Network management, while important for keeping the overall IT environment running, focuses on maintaining connectivity and performance of the communication networks. It isn’t part of the decision-support functionality itself, which is why it isn’t listed as a major DSS component.
