Data mining vs 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.
How is Data Mining different from query tools?
| 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.
