Abstract—this paper is a review study and survey report of
the big data, how it’s been utilized in this days by the
companies and making benefits from it by analyzing the big
data using different tools, which comes through the
customers activities. Although this report is based on the
survey report of year 2011 but it is trend till today. This
report also focuses on the characteristics of the big data and
primary be focused on Big Data Analytics. Two technical
entities have come together. First, there’s big data for
massive amounts of detailed information. Second, there’s
advanced analytics, which is actually a collection of
different tool types, including those based on predictive
analytics, data mining, statistics, artificial intelligence,
natural language processing, and so on. Putting them
together it will be big data analytics, the hottest new practice
in BI (Business Intelligence) today.

I. INTRODUCTION
Oddly enough, big data was a serious problem just a few
years ago. When data volumes started skyrocketing in the
early 2000s, storage and CPU technologies were
overwhelmed by the numerous terabytes of big data—to the
point that IT faced a data scalability crisis. Storage and CPUs
Not only developed greater capacity, speed, and intelligence;
they also fell in price. Enterprises went from being unable to
Afford or manage big data to lavishing budgets on its
collection and analysis. Today, enterprises are exploring big
data to discover facts they didn’t know before. This is an
important task right now because the recent economic
Recession forced deep changes into most businesses,
especially those that depend on mass consumers. Using
advanced analytics, businesses can study big data to
understand the current state of the business and track still-
evolving aspects such as customer behavior. Some big data
sources feed data unceasingly in real time. Put all that
together, and we can see that big data is not just about giant
data volumes; it’s also about an extraordinary diversity of
data types, delivered at various speeds and frequencies.
Big data analytics is where advanced analytic techniques
operate on big data sets. Hence, big data analytics is really
about two things—big data and analytics—plus how the two
have teamed up to create one of the most profound trends in
business intelligence (BI) today.
II. LITERATURE REVIEW
[1] in this article”Trends in big data analytics” written by
Karthik Kambatla in July 2014, we provide an overview of the
state-of-the-art and focus on emerging trends to highlight the
hardware, software, and application landscape
Of big-data analytics.
[2] In “The value of Big Data: How analytics differentiate
winners “written by Bain Brief in September 17, 2013 shares the
survey done by themon howmuch of companies and industries
are utilizing the Big data by analyzing it with advance tools.As
per the report only the 4% of companies are really good at
analytics, an elite group that puts into play the right people,
tools, data and intentional focus. These are the companies that
are already using analytics insights to change the way they
operate or to improve their products and services. And the
difference is already visible.

different from gold — it is firstly, and ultimately, a
commodity.
III. METHODOLOGY
1) Defining advanced analytics as a Discovery Mission
According to a 2009 TDWI survey, 38% of organizations
surveyed reported practicing advanced analytics, whereas 85%
said they would be practicing it within three years.1 Why the
rush to advanced analytics? First, change is rampant in
business, as seen in the multiple “economies” we’ve gone
through in recent years. Analytics helps us discover what has
changed and how we should react
Second, as we crawl out of the recession and into the recovery,
there are more and more business opportunities that should be
seized. To that end, advanced analytics is the best way to
discover new customer segments, identify the best suppliers,
associate products ofaffinity, understand sales seasonality,and
so on.For these reasons,TDWIhas seen a steady streamof user
organizations implementing analytics in recent years.
User organizations are implementing specific forms of
analytics, particularly what is sometimes called advanced
analytics. This is a collection of related techniques and tool
types, usually including predictive analytics, data mining,
statistical analysis, and complex SQL.
Instead of “advanced analytics,” a better term would be
“discovery analytics,” because that’s what users are trying to
accomplish. (Some people call it “exploratory analytics.”) In
other words, with big data analytics, the user is typically a
business analyst who is trying to discover new business facts
that no one in the enterprise knew before. To do that,the analyst
needs large volumes of data with plenty of detail. This is often
data that the enterprise has not yet tapped for analytics.
For example, in the middle of the recent economic recession,
companies were constantly being hit by new forms of customer
churn. To discover the root cause of the newest form of churn,
a business analyst would grab several terabytes of detailed data
drawn from operational applications to get a view of recent
customer behaviors. The analyst might mix that data with
historic data from a data warehouse.Dozens of queries later, the
analyst would discover a new churn behavior in a subset ofthe
customer base. With any luck, that discovery would lead to a
metric, report, analytic model, or some other product of BI,
through which the company could track and predict the new
form of churn.
2) Defining Big Data via the Three Vs.
Most definitions of big data focus on the size of data in storage.
Size matters, but there are otherimportant attributes of big data,
namely data variety and data velocity. The three Vs of big data
(volume, variety, and velocity) constitute a comprehensive
definition, and they bust the myth that big data is only about
data volume. In addition, each of the three Vs has its own
ramifications for analytics.(Figure 1(a)).
2.1) Data volume as a defining attribute of big data.
It’s obvious that data volume is the primary attribute of big
data. With that in mind, most people define big data in
terabytes—sometimes petabytes. For example, a number of
users interviewed by TDWI are managing 3 to 10 terabytes
(TB) of data for analytics. Yet, big data can also be quantified
by counting records, transactions, tables, or files. Some
organizations find it more useful to quantify big data in terms
of time. For example, due to the seven-year statute of
limitations in the U.S., many firms prefer to keep seven years
of data available for risk, compliance, and legal analysis.
USER STORY: There are various ways to quantify big data;
TDWI asked a user how many terabytes he’s managing for
analytics, and he said: “I don’t know, because I don’t have to
worry about storage. IT provides it generously,and I tap it like
crazy.” Anotherusersaid:“We don’t count terabytes.We count
records. My analytic database for quality assurance alone has 3
billion records. There’s another 3 billion in other analytic
databases.”
2.2) Data type variety as a defining attribute of big data.
One of the things that makes big data really big is that it’s
coming from a greater variety of sources than ever before.
Many of the newer ones are Web sources, including logs,
clickstreams, and social media. Sure, user organizations have
been collecting Web data for years. But, for most organizations,
it’s been a kind of hoarding.
The recent tapping of these sources foranalytics means that so-
called structured data. is now joined by unstructured data (text
and human language) and semi structured data (XML, RSS
feeds). There’s also data that’s hard to categorize, as it comes
from audio, video, and other devices That’s a far more eclectic
mix of data types than analytics has everseen.So,with big data,
variety is just as big as volume. In addition, variety and volume
tend to fuel each other.
Figure 1(a): The three Vs of big data

USER STORY: Hadoop is about data variety not just about
the data volume; TDWI found a couple of users who have
employed Hadoop as an analytic platform. Both said the same
thing: Hadoop’s scalability for big data volumes is impressive,
but the real reason they’re working with Hadoop is its ability to
manage a very broad range of data types in its file system, plus
process analytic queries via MapReduce across numerous
eccentric data types. It’s not just Hadoop; TDWI has heard
users make similar comments about other analytic platforms.
2.3) Data feed velocity as a defining attribute of big data.
Big data can be described by its velocity or speed. It can be
prefer to think of it as the frequency of data generation or the
frequency of data delivery. For example, think of the stream of
data coming off of any kind of device or sensor, say robotic
manufacturing machines, thermometers sensing temperature,
microphones listening for movement in a secure area, or video
cameras scanning for a specific face in a crowd. The collection
of big data in real time isn’t new; many firms have been
collecting clickstream data from Web sites for years, using
streaming data to make purchase recommendations to Web
visitors.
USER STORY: Processing streaming big data enables new
analytics applications; A consultant who specializes in
streaming data told TDWI about the video and audio analytic
applications he’s looking into: “Think about the algorithms that
enable us to parse text and perform sentiment analysis,
sometimes in real time. Very similar algorithms can parse video
images to document and analyze changes in the thing that’s
being imaged. For example, satellite images could monitor and
analyze troop movements, a flood plane, cloud patterns, or
grass fires. Or a video analysis systemcould monitor a sensitive
or valuable facility, watching for possible intruders, then alert
authorities in real time.
3) Big Data analytics adoption
Big data analytics is a fast-growing and influential practice. But
how many userorganizations are actually doing it? To find out,
this report’s survey asked respondents:“Does yourorganization
execute advanced analytics against big data today?”
Advanced analytics is fairly common today. Roughly three
quarters (74%) of organizations surveyed have adopted some
form of analytics today, regardless of the analytic method or
tool type, whether with big data or not. This reveals a strong
adoption of advanced analytics, which isn’t a surprise, given
that it’s been around for at least 15 years.
Analytics doesn’t require big data. The two get jammed into
the same sentence so much lately that we forget that they don’t
have to go together.In fact, 40% of survey respondents practice
advanced analytics without big data.
Figure 2. Based on 325 respondents
4) Big Data: Problem or Opportunity? TDWI has seen many
userorganizations emerge only recently from a scalability crisis
where big data was more of a curse than a blessing. With that
in mind, we asked: “In yourorganization, is big data considered
mostly a problem or mostly an opportunity? “Only 30%
consider big data a problem. There’s no doubt that big data
presents technical challenges due to its volume, variety, and
velocity. Data volume alone is a showstopper for some
organizations. The vast majority (70%) considers big data an
opportunity.Through exploratory, detailed analyses ofbig data,
a user organization can discover new facts about their
customers, markets, partners, costs, and operations—then use
that information for business advantage
Figure 3. Based on 325 responses
5) Managing analytic Big Data
One of the big questions for big data is: Where should you
manage it and operate on it? After all, there are many
vendor-built database platforms available today that can
handle large analytic data sets. And user organizations have
diverse business and technology requirements that lead them
to equally diverse designs, models, and architectures. To get
a sense of what users think about these issues, this report’s
survey asked a pair of related questions: Today, where is big
data for advanced analytics managed and operated on?
Where would you prefer that big data for advanced analytics
be managed and operated on?

Figure 4: Based on 325 respondents
Concerning the list of big data analytics options, the survey
asked: “What kinds of techniques and tool types is your
organization using for advanced analytics and big data, both
today and in three years?” Survey responses for these two
questions are charted as pairs of bars on the left side of
Figure 16. Within each pair of bars, the value for Using
Today is the percentage of survey respondents who claim to
use that option now. Similarly, the value of Using in Three
Years is the percentage of surveyrespondents who anticipate
using that option in coming years. The pairs of bars on the
right side of Figure 5 portray a slightly different view of
option usage. The Potential Growth bars calculate the per-
option difference between responses for Using Today and
Using in Three Years; this delta provides an indication of
how much the usage of a big data analytics option will
increase or decrease. An option’s Commitment value is the
percentage of survey respondents who are committed to
using that option, whether today, in three years, or both.

respondents. The charts are sorted by the “Potential
Growth” column of values
III. CONCLUSION
Big data has impact very greatly in today’s era of technology
as some of the companies still can’t make the benefits out of it
but more than 80% of the year of this 2017 has started earning
benefits by making best decisions on the speed of time As the
chart below shows the impact of big data analytics on various
background of industries.
