How do you extract value from vast quantities of heterogeneous data? The article introduces Data Mining as a key to reading Big Data, starting from the "3Vs" that characterize them: volume, velocity and variety.
Particular attention is paid to variety — structured, semi-structured and unstructured data — and how it deeply influences management and analysis. From relational databases organized in rows and columns to messier sources, the article explains the process of discovering patterns, relationships and meaningful information hidden in data, which is the heart of Data Mining. In the full PDF: the types of data and the Data Mining process.
