Big data is a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. The challenges include capture, curation, storage, search, sharing, transfer, analysis, and visualization. The trend to larger data sets is due to the additional information derivable from analysis of a single large set of related data, as compared to separate smaller sets with the same total amount of data, allowing correlations to be found to "spot business trends, determine quality of research, prevent diseases, link legal citations, combat crime, and determine real-time roadway traffic conditions."

我觉得wikipedia上那句话已经够清楚了。再解释也只是用家常话同义重复而已。‘大数据’概念本身强调的是处理大数据的能力和技术，大数据的应用价值不在于它‘大’，而在于其细粒度信息的价值（微观干预的能力）
