Data mining is the process of analyzing large amounts of data to find
useful patterns, trends, and insights. It helps businesses make better decisions.
It is used in many industries such as retail, healthcare, finance,

- Clustering – Grouping similar data (e.g., customer segments)
- Association – Finding relationships (e.g., items bought together)
- Regression – Predicting values (e.g., future sales)
- Outlier Detection – Finding unusual data (e.g., fraud cases)
