The process of extracting information to identify patterns, trends, and useful data that would allow the business to take the data-driven decision from a huge set of data is called data mining. It can also be defined as the process of discovering meaningful new correlations, patterns, and trends by mining large amounts of data stored in the warehouse using artificial intelligence, statistical and mathematical techniques.

Need of Data Mining

As we know today, the growth of data is moving from terabyte to petabyte, hence storing that data and getting some useful information from that data is the process of data mining.

Technologies Used in Data Mining

  • Machine learning
  • Pattern recognition
