The term "Big Data" become popular in last few
years, as it represents the hard work of researchers to achieve
business intelligence by processing tremendously large
amount of data. To collect, store, manage and analyse it is
very difficult for typical dataset software tools. Of course big
data is too large to load into memory and store on a hard-drive
and fit in a standard database.[1] Big data extents three
dimensions: Volume, Velocity and Variety. Organizations
from retail to wholesalers and Enterprises are overburdened
with growing data of all types and in petabytes of information.
Which leads the rapid increase in big data size called volume.
Time -sensitive processes leads to the timely data response of
big data called velocity. All Variety of data such as text,
audio, video, click streams, sensor data, log files and news
will lead to classify the data in three category. Structured,
Semi-structured and unstructured. Researchers find the
insights by analyzing these data types together.[7]
From banking to retail many sectors have already
embraced big data traditionally. Industries taking advantage of
big data by gaining deeper insights. It is very important as the
emergence of cloud computing and the demand of analysing
massive data arisen. Data increase in terms of peta bytes to
thousands of gigabytes the ability of handling big data become
so essential that nobody can mistreat it. [2] The definition of
big data may vary depending upon the application and kind of
tools and techniques available. Big data may be considered as
"digital breadcrumbs", which we left behind our every
communication transaction and then we need to analyze it for
better business. Sometimes big data is less about the data and
more about the analytics. [9]The information that we filter
from the data will drive you to proper solution. To acquire an
actual meaning of the face-book status is important than the
just an updated status.
Even though industry hype, most of institutions and
organizations have yet to develop, implement a big data policy
[4]. SAS (leading business analytics Software Company) had
carried out one survey in July 2013. Survey was conducted on
339 companies with thorough experience in data management
strategy and execution. They were asked few questions based
on the usage of tools and technology for data management in
their existing organization. For total sample size, 95%
confidence level was set and thus marginal error was +/- 5.3.
The survey clearly mention (as shown in figure:1) 39% of the
organizations are currently exploring big data environment. It
is found that 12 percent of organizations have considered big
data strategy and they are in Execution/Implementation phase.
Unexpectedly, by eliminating those who don't know or do not
consider and not already implementing, testing or planning
