Aug 13, 2021 Data mining collects, stores and analyzes massive amounts of information. To be useful for businesses, the data stored and mined may be narrowed down to a zip code or even a single street. There are companies that specialize in collecting information for data mining. They gather it from public records like voting rolls or property tax files.
In principle, data mining is not specific to one type of media or data. Data mining should be applicable to any kind of information repository. However, algorithms and approaches may differ when applied to different types of data. Indeed, the challenges presented by different types of data vary significantly.
