Also known as business intelligence (BI) software, ___ support system (DSS) software gained credibility with airlines and air traffic control systems in the mid-1980s and 1990s.

• A. Data
• B. Logic
• C. Rule
• D. Decision

Answer: (D)

Decision support systems are tools that help people make better choices by combining data, models, and interactive analysis. As BI software, they provide the kind of analysis and visualization that supports decision-making across complex, semi-structured problems. In the mid-1980s and 1990s, airlines and air traffic control embraced these systems because they could integrate data, run models for forecasting, scheduling, and routing, and enable what-if scenarios before committing resources. That practical value cemented the established term in this field: Decision support system. The other options don’t form the standard name for this class of software, which is why “Decision” is the best fit.
