Big data describes a large amount of data in a structured and unstructured way. The data belongs to different organizations and each organization uses this data for different purposes.

Big data is a large and complex data set and traditional data processing applications are not sufficient to handle big data. Managing such a huge volume of data (e.g., capturing, storing, data analyzing, data transferring, data ****enjoying, etc.) is a challenge. Big data follows the 3V model of high volume, high velocity, and high diversity.
