Data Mining
TL;DR Data mining is the practice of discovering useful patterns, trends, and insights hidden within large collections of data.
Data mining is a foundational concept in data science and artificial intelligence, focused on extracting meaningful information from large and complex datasets. As organizations generate enormous volumes of data from digital systems, sensors, transactions, and user activity, data mining provides systematic methods for uncovering relationships and patterns that are not immediately apparent. These insights inform decisions, improve efficiency, and predict future outcomes across many industries.
Data mining is the process of searching large volumes of data to uncover valuable insights. Companies use data mining to understand customer behavior, spot trends, reduce fraud, and improve services. For example, a retailer might analyze purchase data to identify which products are often purchased together, while a bank might look for anomalous patterns that signal fraud. The goal is not just to collect data but to turn it into knowledge that helps people make better choices.
From a technical perspective, data mining involves applying statistical techniques, machine learning algorithms, and pattern recognition methods to analyze large datasets. It includes tasks such as classification, clustering, association rule mining, anomaly detection, and regression. Data mining often operates as part of a broader pipeline that provides for data cleaning, transformation, and evaluation, and it overlaps with fields such as machine learning, database systems, and big data analytics. The emphasis is on discovering previously unknown or non-trivial patterns that are both statistically valid and practically useful.

ELI5 Data mining is like digging through a large volume of numbers to find hidden patterns. You look carefully at all the information to spot patterns that help you understand what is happening or what might happen next.
