Abstract: We are in a world of increasing data, the day-by-day generation of data becomes very vast. The true of it lies in collecting these data, analyze and perform some computations to obtain some meaningful information. These meaningful information can be derived using some data mining tasks. In short we can call big data as an ’asset’ and data mining is a ‘handler’ that is used to provide beneficial results. To perform these analysis data mining algorithms can be used and also the big data methods.

Keywords: Big data, Data Mining, HACE theorem, structured and unstructured.
