  • What „google” says? The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use.
  • What „google” says? Aside from the raw analysis step, it involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating.
