-Data volumes that are exceptionally large, normally greater than 100 Terabyte and more commonly refer to the Petabyte and Exabyte range. Big data has begun to be used when discussing Data Warehousing and analytic solutions where the volume of data poses specific challenges that are unique to very large volumes of data including: data loading, [[data_management/data_modeling|modeling]], cleansing, and analytics, and are often solved using massively parallel processing, or parallel processing and distributed data solutions.
