What is Big Data!

Big data is actually too much of data. It is large amount of structures and unstructured data which is difficult for traditional software tools to capture, curate, manage, and process. It ranges from a few dozen terabytes to many petabytes of data in a single data set. Big data may be in petabytes (1,024 terabytes) or exabytes (1,024 petabytes) and consists of billions to trillions of records of millions of people. Areas like meteorology, connectomics, genomics, complex physics simulations,and biological and environmental research usually have large data sets. It has become very difficult for organisations to manage big data. Big data is very important for businesses as well as society and has raised the need to reconstruct data management systems.
