Overview of Data Mining Applications. Data mining is how the patterns in large data sets are viewed and discovered using intersecting techniques such as statistics, machine learning, and ones like databases systems. It involves data extraction from a group of raw and unidentified data sets to provide some meaningful results through mining.

Data mining is the process of discovering actionable information from large sets of data. Data mining uses mathematical analysis to derive patterns and trends that exist in data. Typically, these patterns cannot be discovered by traditional data exploration because the relationships are too complex or because there is too much data.
