Data mining techniques are used for a long process of research and product development. This evolution was started when business data was first stored on computers. One can also navigate through their data in real time and get insights about data for data-driven decisions. Data Mining is also popular in the business community. This is supported by three technologies that are now mature: Massive data collection, Powerful multiprocessor computers, and Data mining algorithms.
