Talking about ‘big data' refers to datasets that are either extraordinarily large or have a complex structure. These traits may sometimes be accompanied by more difficult data storage, processing, and application of following activities, or the extraction of discoveries. The practice of doing analytics on massive, complex datasets, sometimes known as ‘big data,' is a method that may be utilized to discover links and patterns in these datasets that were previously undiscovered. However, attempts to protect the privacy and security of big data are undermined by its rapid spread.
