=====Big data=====

===Definition===
Big data is [[data_concept:data|data]] that contains greater [[data_quality_dimension/variety|variety]], arriving in increasing volumes and with more velocity.

===DMBoK2===
Big Data is the collection (generated and stored) of increasing volume of varied data from many different types and sources of data.

===DDDM===
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_management/data_warehouse|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]], [[data_quality_management_system/data_cleansing|cleansing]], and analytics, and are often solved using massively parallel processing, or parallel processing and distributed data solutions.
