The 45V characteristics of Big Data: Volume (large amount), Velocity (high speed), Variety (diverse), veracity (authenticity). Big Data requires special technologies, including massively parallel processing (MPP) databases, data mining grids, distributed file systems, distributed databases, cloud computing platforms, the Internet, and scalable storage systems.
