Which of the following operations belong to data mining?

Predicting which customers will buy and spotting anomalous network packets are classic data-mining tasks: they require modeling patterns and making inferences beyond simple database retrieval.

1. Relevant knowledge points and concepts
- Data mining = discovery of patterns, models, or predictions from large datasets (supervised learning, unsupervised learning, anomaly/outlier detection, association rules, clustering).
- Simple database queries (selection/projection) retrieve records satisfying explicit conditions; they are not “mining” because they do not infer new patterns or build predictive models.

2. Step-by-step reasoning process
- Option A (predict customers who may buy in next 3 months): This requires using historical purchase and behavior data to learn a predictive model (classification or survival/regression modeling). It’s a predictive analytics/data-mining task.
- Option C (find abnormal network packets based on normal patterns): This is anomaly detection—learn normal traffic patterns then identify deviations. That is an unsupervised/supervised data-mining task.
- Option B (find all cars > $3000): This is a straightforward selection query (SQL WHERE price > 3000). No pattern discovery or model building—just retrieval.
- Option D (find all engineering students with GPA > 3.5): Similarly, this is a direct database query/filter, not data mining.

3. Intermediate “calculation” steps (conceptual mapping)
- For A: collect features (past purchases, demographics, browsing), label outcomes (bought/not), train classifier → predict probability of purchase.
- For C: model normal packet features (e.g., packet size, timing) → compute deviation score → flag packets above threshold.

4. Why the correct answers are correct
- Both selected options require inferring unknowns from patterns in data (prediction or anomaly detection), which is the essence of data mining.

5. Why other options are incorrect
- Options B and D are deterministic filters/queries that do not build models or discover hidden patterns; they belong to data retrieval, not data mining.

6. Conclusion
- Therefore the correct data-mining operations are: “Find customers who may buy a certain product in the next three months” and “Find network packages that are abnormal based on the normal patterns,” matching the provided answer.
