Big data applications solve and
analyze real world problems using Hadoop and associated tools. Internet users
and machine-to-machine connections are causing the data growth. Real time areas
are defined following in which big data is used:
A. Big data
in healthcare
Healthcare practices and policies
differ tremendously around the world, there are three objectives regarding
healthcare system [10]. The first objective is to improve the patient
experience (including quality and satisfaction). Second, improving overall
population health and reducing the cost of health care and third is traditional
methods have fallen short to manage health care and create modern technology to
analyze large quantities of information. It is time consuming for clinical
staff to Collecting massive amounts of data in healthcare. High-performance
analytics are new technologies making easier to turn massive amounts of data
into relevant and critical insights used to provide better care. Analytics
helps to predict negative intervene and reactions. Unstructured data can be captured
through text mining from patient records. It means information can be
collecting without causing additional work for clinicians. Transparent,
information can thus improve encourage and quality innovation. A massive amount
of data collected from different sources provides the best practices for today,
and will help healthcare providers identify trends so they can achieve better
results to improve medical facilities all around the world.
B. Network
Security
Big data is changing the landscape of
security technologies. The tremendous role of big data can be seen in network
monitoring, forensics and SIEM [11]. Big data can also create a world where
maintaining control over the revelation of our personal information is
challenged constantly. Present analytical techniques don’t work well at large
scales and end up producing false positives that their efficacy is undermined
and enterprises move to cloud architectures and gather much more data, the
problem is becoming worse. Big data analytics is an effective solution for
processing of large scale information as security is major concern in
enterprises. Fraud detection is uses for big data analytics. Phone and credit
card companies have conducted large-scale fraud detection for decades. Mainly
big data tools are particularly suited to become fundamental for forensics and
ATP.

C. Market and
business
Big Data is the biggest game-changing
opportunity for sales and marketing, since 20 years ago the Internet went main stream,
because of the unprecedented array of insights into customer needs and
behaviours it makes possible [12]. But many executives who agree that this is
true aren’t sure how to make the most of it and they also find themselves faced
with overwhelming amounts of data and rapidly changing customer behaviours,
organizational complexity and increased competitive pressures. According to
Gartner, 50% internet connection between Internet of things (IoT) devices and
number reached over 15 billion in 2011 and 30 billion by 2020[18]. Some
companies are succeeding at turning that Big Data promise into reality. Those
that use Big Data and analytics effectively show profitability and productivity
rates that are 5–6% higher than those of their peers. The companies that
succeed aren’t the ones who have the most data, but the ones who use it best.
Marketing of big data provides a strategic road map for executives who want to
clear the chaos and start driving competitive advantage and top line growth.
Using realworld examples additional downloadable resources, non-technical
language, and a healthy dose of humour will help you discover the remedy
offered by data-driven marketing. These insights to insure your business's success.

D. Sports
Sport, in business, an increasing
volume of information is being collected and captured. Technological advances
will fuel exponential growth in this area for the foreseeable future, as
athletes are continuously monitored by tools as diverse as sports daily saliva,
GPS systems and heart rate monitors tests. These statistics and many more like
them are high performance in Big Data. These numbers there is a massive amount
of potential insight and intelligence for trainers, administrators, coaches,
athletes, sports medics and players. Statistics can be analyzed and collected
to better understand what are the critical factors for optimum performance and
success, in all facets of elite sport. Injury prevention, competition,
Preparation, and rehabilitation can all benefit by applying this approach.
Recruitment, Scouting and retention can also be enhanced by these powerful
principles. Keeping an eye on various information a coach or a manager can
easily and quickly understand which athletes and players need additional
support, training, and guidance. Areas for reasons for success and improvement
will be understood more clearly. Used consistently this is a powerful measure
of progress and performance.

E. Education
Systems
By using big data analytics in field
of education systems, remarkable results can be seen . Data on students online
behaviour can provide educators with important insights, such as if a student
requires more attention, the class understanding of a topic is not clear, or if
the course has to be modified. Students are required to answer accompanying
questions as they go through the set of online content before class. By
tracking the number of students that have completed the online module, the time
taken and accuracy of their answers, a lecturer can be better informed of the
profile of his students and modify the lesson plan accordingly. The analysis of
data also clarify about the interest of student looking at time spent in online
textbook, online lectures, notes etc. As result instructor can guide choosing
the future path effectively.

F. Gaming
industry
The amount of data that video game
players are generating on a daily basis is growing rapidaitely. Video game
developers are using variety of IT techniques such as Hadoop to keep up the
massive amount of gamingdata that’s generated every day. People are playing
video game and generated lot of data in separate areas: game data, player data
and session data. In order to improve their game development, game experience,
studios are turning to commercial Hadoop distributions such as MapR to analyze,
collect and process data from these massive data streams. Armed with this
valuable insight from big data, video game publishers are now able to enhance
game player engagement and increase player retention by analyzing gamers’
social behaviour, activity and tracking players’ statistics, calculating
rewards, quickly generating leader boards, changing game play and mechanics and
delivering virtual prizes, so that experienced players will continue to play
the game.Today big challenges for telecommunication are volume, variety and
complexity. Current data systems based on batch processing and traditional
relation technology, they process big data in real time. Telcos combine ETL and
traditional relational databases with big data technologies on a single
platform. Telcos technology parses, transforms and integrates the vast amount
of data generated by location sensors, IPv6 devices, clickstream, CDRs, 4G
networks and machine to machine monitors’ information. Cloud data integration
helps to control over off-premise data managed in the cloud.
FUTURE
SCOPE
The new applications are generating
vast amount of data in structured and unstructured form. Big data is able to
process and store that data and probably in more amounts in near future.
Hopefully, Hadoop will get better. New technologies and tools that have ability
to record, monitor measure and combine all kinds of data around us, are going
to be introduced soon. We will need new technologies and tools for anonymzing
data, analysis, tracking and auditing information, sharing and managing, our
own personal data in future. So many aspects of life health, education,
telecommunication, marketing, sports and business etc that manages big data
world need to be polished in future.
