Applied Big Data Analytics
by Mr ajit kumar roy (Author)
Big Data is the expression of this gigantic mass of information that we are
constantly generating at the global level. Now the buzzword “big data” refers
to the new data-driven paradigm of business, science and technology, where the
huge data size and scope enables better and new services, products, and
platforms. It is estimated that the total accumulated data stored on computers
worldwide is about 300 exabytes.The annual transmission of data is estimated at
about 1.9 zettabytes i.e.1900 billion gigabytes. It is believed that Big Data
is one of those mega trends that will impact everyone in one way or another.
Due to the tremendous amount of data generated daily from fields such as
business, research, and sciences, big data is everywhere and represents huge
opportunities to those who can use it effectively. In the past, this
information was simply ignored and opportunities were missed. Realizing the
great importance of big data, organizations scramble to find hidden information
buried in big data and try to make the best use of it. Presently “big data” is
a hot topic and getting a lot of media and business attention. Collecting,
analyzing and understanding Big Data is becoming a differentiated strategy
today but it will become a fact of life tomorrow. Running analyses at the
finest granularities while you still have enough data for the results to be
meaningful and accurate leads to more precise action and in turn more profits
and savings for the company and customers. Over recent times, the concepts of
“big data” and “big data analytics” have become ubiquitous. It is hard to visit
a web site, open a newspaper, or read a magazine that does not refer to one or
both of those phrases. Yet the technologies that are incorporated into big data
are massive parallelism, huge data volumes, data distribution, high-speed
networks, high-performance computing and data mining and analytics. Big Data is
the result of practically everything in the world being monitored and measured;
creating data faster than the available technologies can store, process or
manage it. Presently there has been a surge of unstructured data, making up as
much as 80% of new data that requires attention for management. Big Data
results in three basic challenges: storing, processing and managing it
efficiently. To tackle the challenges of Big Data, novel approaches and tools
have emerged. The technology required for big-data computing is developing at a
satisfactory rate due to market forces and technological evolution. This book
entitled 'Applied Big Data Analytics' presents a mix of theory and real world
cases that discuss the technical and practical issues related to Big Data
application aiming intelligent information management. This book covers rich
topics of sources of big data generation, analytical tools, and utilization for
extracting valuable insight out of scientific study. The edited book reveals
how to fully apply the tools and techniques in various fields. The book will
certainly be invaluable to wide audiences of professionals, decision-makers,
and consultants involved in analytics particularly the new comers in the areas.
It will also be exceptionally useful to students of analytics in any graduate,
undergraduate, or certificate program. The project could not have been
successful without the whole hearted support of the valued contributors of the
book. Simply, I am grateful to all of them.
