If the warehouse is the library, data mining is the researcher. Data mining is the process of discovering hidden patterns, correlations, and anomalies within large datasets. It relies on sophisticated algorithms drawn from statistics, machine learning, and artificial intelligence. Key principles of data mining include:

Predicting future trends or categorizing data into predefined groups (e.g., "will this customer churn?").

Grouping data points that share similar characteristics without prior labeling (e.g., identifying market segments).

Discovering "if-then" relationships, such as the famous observation that customers who buy diapers often buy beer. Synergy and Applications
