The three major components in any DSS include the data warehouse, the decision support model, and the ___ interface.

• A. User
• B. Database
• C. Hardware
• D. Software

Answer: (A)

A decision support system is most effective when there’s a clear way for people to interact with it. The data warehouse stores and organizes the data, the decision support model applies analytics to turn that data into insights, and the user interface is the bridge that lets users input assumptions, run models, and view results. Without the interface, the powerful data and models can’t be used to support decisions. The other terms—database, hardware, and software—refer to broader parts of IT infrastructure or storage, not the specific interactive layer that completes the DSS trio.
