Which system uses a knowledge base and a set of rules to analyze data and provide recommendations?

• A. Decision Support Systems
• B. Knowledge Generator
• C. Wisdom Wizards
• D. Benchmarkers

Answer: (A)

Systems that integrate a knowledge base with a set of rules to analyze data and provide recommendations are designed to support decision making by applying encoded expertise to current data. A Decision Support System uses stored domain knowledge and a rule base (if-then logic) along with an inference engine to interpret data from various sources and generate actionable recommendations. This helps users move from raw numbers to informed choices, whether in healthcare, business, or operations, by highlighting relevant patterns and suggested courses of action rather than just presenting data. The other terms described don’t correspond to established systems that combine knowledge and rules to produce recommendations; they don’t capture the standard idea of structured rule-based analysis used to guide decisions.
