Big Data Analysis: History, Challenges, Characteristics, and Business Usage

This presentation provides an overview of Big Data Analysis, including its history, challenges, characteristics, and business usage. It also covers techniques like A/B testing, machine learning, and data mining. The presentation cites references from various sources to support the information presented.

History on Big
Data
Concept of big data has
been founded by data
management pundits.
John Graunt had dealt
with huge amount of data
for which he started usage
of statistics in 1663.
Hence, he was honoured
as a first person to use
statistical data analytics.

What is Big Data
Big data may be referred as larger data sets which may only be
analysed with the help of Big data tools in order to reveal human
behaviour, marketplace trends and its patterns and much more. It
is a concept implies larger and complexing data sets which are
processed up with data processing applications & software. Data is
a term refers to raw material, i.e, unprocessed data.
Characteristics of Big data
Volume- The Quantity of data provides an insight that
the data must be considered Big data or Not. If Such
data is large enough and involves much complexities
require a number of data analytics techniques to
process it, then it is classified as big data.
Variety- Traditionally, RDBMS was enough to handle
the stored larger data easily. But as changes occurred
in data types and their structures, traditional data
analytics techniques were challenged as then Big Data
Came into Play.
The challenges of big data
analytics
Incorrect analytics: If the firm has wrong and defective
data, the analysis done on such data would result in
defective results which eventually impact the validity
and authenticity of the data. Sometimes the system has
some errors due to the omission at the time of
development and testing of it which increases the
problems related to processing of the data.
Security issues: The tools that are being used for the
analysis uses various sources to extract the data that
could make the data vulnerable. Hence, increase in the
data would increase the security issues related to the
data.
Lack of understanding: The demand for the analysts are
ever increasing due to continuous rise in the data that is
being created. It has now became a crucial responsibility
of the business to appoint a data analysts who acquires
the skills of properly analysing the data of the firm.

How Big Data technology could
support business & Examples
In business usage terms, Big data may be referred to
processes and tools for utilization and management of
a large data set. It can be very helpful to create new
services and products for a grand consumer
experience. example:
Big Data in healthcare industry: Under this Companies
then on basis of trial data frame risks and beneficial
outcome to its users.
Techniques that are currently available
to analysis big data
A/B Testing: It is a technique that compares the control group
with the different test groups to identify what changes can be
adopted to improve the main variable for which the analysis is
done.
Machine Learning: It is a software that helps the computer to
learn new programs and it makes predictions of the data or make
assumptions based on the entered data.
Data Mining: It is a technique used on large amount of data to
draw out a pattern with the help of combination of two
techniques, i.e., machine learning & statistics within the
framework of management of database.
