4 v in bigdata
Bigdata is usually transformed in three dimensions- volume, velocity and variety.
Volume: Machine generated data is produced in larger quantities than non traditional data.
Velocity: This refers to the speed of data processing.
Variety: This refers to large variety of input data which in turn generates large amount of data as output.
Veracity: Data in doubt.
Evolution of Big Data
1990:OLAP and data warehousing
2000:Batch processing and Distributed data store(Big data)
2010:Real time and single View (Big Data)
