amounts of data of a variety of types (big data) to
uncover hidden patterns, unknown correlations and
other useful information.
Such information can provide competitive advantages
over rival organizations and result in higher business
intelligence or scientific discovery, such as more
effective marketing, increased revenue, etc.
The primary goal of big data analytics is to help
companies make better business decisions by enabling
data scientists and other users to analyze huge volumes
of transaction data that may be left untapped by
conventional business intelligence (BI) programs.

Internet clickstream data, social media activity reports,
mobile-phone call records and information captured by
sensors or IoT devices. 10 Unstructured data sources used for big data
analytics may not fit in traditional data warehouses.
Traditional data warehouses may not be able to
handle the processing demands posed by big data. Some people exclusively associate big data and big data
analytics with unstructured data. The new technologies associated with big data
analytics include NoSQL databases, Hadoop and
MapReduce. These technologies form the core of an
open-source software framework that supports the
processing of large data sets across clustered
systems or datacenter-converted clouds. Consulting firms like Gartner and Forrester Research
consider transactions and other structured data to be
valid forms of big data.
Big data analytics can be done with the software tools
commonly used as part of advanced analytics disciplines
such as predictive analytics and data mining.
