Data mining is the process of analyzing data to extract information not offered by the raw data alone. Data mining can also begin at a summary information level (coarse granularity) and progress through increasing levels of detail (drilling down), or the reverse (drilling up). Data mining occurs on structured data that are already in a database or a spreadsheet. Unstructured data do not exist in a fixed location and can include text documents, PDFs, voice messages, emails, and so on. Three common forms for mining structured and unstructured data are cluster analysis, association detection, and statistical analysis.
