Information Systems and Big Data Analysis
What is big Data
Big data is the collection of different types of data which are huge in volume as
well as growing with exponentially with specific period of time. It is considered
as the data in large size as well as complexity that can not be store and process by
the traditional management tool in efficient manner. In current competitive and
advanced technological world, big data is the effective tool and technique which

business different types of Big Data technologies are implemented by the
organisation such as Hive, Cloud and Spark, SQL and various other (Chang,
2018). It includes assessment of different factors which are related to data storage
and management which is important for the growth, development and
synchronization of business data.
