Because of enormous growth of information in this age of networking & info distribution, manually evaluating, categorising, & summarising data is difficult. As a result, subjects like big data & data mining are frequently explored. Data mining is procedure for dig out info from huge amounts of data in order to create a pattern or anomaly. In order to create innovative approaches for incorporating uncertainty management into data mining, this research looks into basics of data mining as well as existing research on integrating uncertainty into data mining.  Management of indeterminate data, which might be instigated by obsolete resources, specimen mistakes, or inaccurate calculations, is among most difficult issues for technologies of data mining.  Development of noval approaches for adding uncertainty supervision into data mining will be a focus of future study.
