<P> Big data is a term used to refer to data sets that are too large or complex for traditional data - processing application software to adequately deal with . Data with many cases (rows) offer greater statistical power, while data with higher complexity (more attributes or columns) may lead to a higher false discovery rate . Big data challenges include capturing data, data storage, data analysis, search, sharing, transfer, visualization, querying, updating, information privacy and data source . Big data was originally associated with three key concepts: volume, variety, and velocity . Other concepts later attributed with big data are veracity (i.e., how much noise is in the data) and value . </P> <P> Current usage of the term "big data" tends to refer to the use of predictive analytics, user behavior analytics, or certain other advanced data analytics methods that extract value from data, and seldom to a particular size of data set . "There is little doubt that the quantities of data now available are indeed large, but that's not the most relevant characteristic of this new data ecosystem ." Analysis of data sets can find new correlations to "spot business trends, prevent diseases, combat crime and so on ." Scientists, business executives, practitioners of medicine, advertising and governments alike regularly meet difficulties with large data - sets in areas including Internet search, fintech, urban informatics, and business informatics . Scientists encounter limitations in e-Science work, including meteorology, genomics, connectomics, complex physics simulations, biology and environmental research . </P>
