Big Data

Big data refers to huge amounts of data that are too large and complex to be analysed using normal data processing methods. Big data is data that has to be processed in special data centres rather than on a home computer. It should be noted, however, that the term 'big data' is not used uniformly and is often also used for technologies that enable the collection and analysis of enormous amounts of data, for example. The official definition of big data refers to four levels:- Volume/scope of data

- Velocity of processing
- Variety of data types
- Veracity of data
