Big Data refers to the new technologies and applications introduced to handle increasing Volume, Velocity and Variety of data while enhancing data utilization capabilities such as Variability, Veracity, and Value.
The large Volume of data available forces horizontal scalability of storage and processing and has implications for all the other V-attributes. The increasing velocity of data ingestion and change implies the need for stream processing, filtering, and processing optimizations. The variety of data types (e.g. multimedia) being generated a requires the use of non-traditional data stores and processing.
