Understanding Big Data and its Challenges for Information Systems and Big Data Analysis

This presentation provides an overview of big data, its characteristics, challenges, and techniques for analysis. It also discusses how big data technology can support businesses with examples. The challenges of big data analytics include lack of knowledge professionals, integrating data from various sources, data growth issues, and lack of proper understanding of the data. Techniques for analysis include A/B testing, data fusion and integration, statistics, natural language processing, and data mining. Big data technology can support businesses by ensuring data safety, identifying consumer preferences, and effective allocation of resources.

History on big Data
The big data is a form of massive data which is having
huge volume and difficult to manage the same. It is a
modern branch of technology which helps in

What is big Data
It can be defined as a set of structured, semi structured and
unstructured information that is collected, stored, sorted by
different enterprises that helps in efficient and effective
decision making process that would facilitate growth and
expansion of organisation. There are various sets that provide

explained as given below:
a.) Volume- The big data is large in volume and carries
variety of data such as homogeneous or heterogeneous
data.
b.) Variety – The data is a raw facts and figures. It can be
either structured, semi structured and unstructured.
c.)Velocity – This term defines the rate at which data is
processed and retrieved from the huge collection of data.
d.)Veracity – It indicates the validity and accuracy of the
big data which helps to take several decisions.

The challenges of big data
analytics
There are various challenges of big data which can be
explained as given below:
• Lack of knowledge professionals – The new
technology require experienced personnel which
creates problem for the organisation to hire them.
• Integrating data from various sources – There are
various sources of collecting data such as PDF, video
and audio.
• Data growth issues – The size of the data is very
huge and it is difficult to handle the same.
• Lack of proper understanding of the data – There are
some data which can not be classified in any
category. Thus, it requires proper sorting of the data. References

How Big Data technology could
support business & Examples
• Data safety – There are numerous data of the
consumers which is kept safely by using various
software and modern technology.
• Dialogue with customers -Every organisation works
with the motive of satisfying consumers which can be
possible by identifying the preferences of the
consumer.
• Optimum utilisation of resources – The resources of
the organisation are scare. Thus, big data technology
helps in effective allocation of resources.
Techniques that are currently
available to analysis big data
1.)a/b testing- It is a technique which helps to compare the
two different web pages and takes decisions regarding the
best performing web page.
2.)data fusion and integration- The analysis of data is done
when data is inspected closely and integration includes the
synthesis of the several components of the data.
3.)Statistics- It is branch of knowledge which collect,
organize and interpret the data to take various decisions.
4.)Natural language processing – It is a language which uses
simple English words and easily understandable by the
humans.
5.)data mining – it is the process of extracting data from
several sources to know the patterns of the consumer.
