## Question

How is Data Mining different from query tools?

## Short answer

Query tools are verification-driven and return records or aggregates the user already knows to ask for. Data mining is discovery-driven and finds hidden patterns, rules, clusters and models, and it supports prediction. Data mining extracts knowledge, not just retrieved data.

## Answer

| Point | Query tools (SQL, report tools) | Data mining |
|---|---|---|
| Approach | Verification-driven: the user knows what to ask | Discovery-driven: finds patterns unknown to the user |
| Output | Records or aggregated values already in the data | Hidden patterns, rules, clusters, models |
| Question | "Which customers bought a laptop in June?" | "Which customers are likely to buy a laptop next?" |
| Prediction | Not supported | Supported |
| Techniques | Selection, join, group-by | Classification, clustering, association, regression |
| User skill | Must write exact queries | Needs a mining task and interpretation |
| Data size | Any | Mostly very large, preprocessed |
| Knowledge | Retrieval of data | Extraction of knowledge |

Query tools answer questions the user already has; data mining finds the questions worth asking.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. Query tools are:
   A. Discovery-driven
   B. Verification-driven: the user knows what to ask
   C. Predictive
   D. Unsupervised
   Answer: B. Query tools answer questions the user already has. (Key point: Approach)

2. Which supports prediction?
   A. SQL queries
   B. Report tools
   C. Data mining
   D. Neither
   Answer: C. Query tools do not predict; mining does. (Key point: Prediction)

3. Which question needs data mining rather than a query?
   A. Which customers bought a laptop in June?
   B. Which customers are likely to buy a laptop next?
   C. Total sales in June?
   D. List all items
   Answer: B. Predicting likely buyers requires discovering patterns. (Key point: Best example for mining)
