2. WHAT IS BIGDATA ?
 Bigdata is a term that describes large volumes of high velocity, complex and
variable data that require advance techniques and technologies to enable the
capture, storage, distribution, management and the analysis of information.
 Bigdata is a data that exceeds the processing capacity of conventional
database systems.
 The data is too big , moves too fast, or doesn’t fit the structures of your
database architecture.
 To gain value from this data, you must choose an alternative way to process
it.

3. BIGDATA ANALYTICS :
 Bigdata analytic is the process of examining and interrogating big data
assets to derive insights of value for decision making.

4. CHARACTERISTICS OF BIGDATA
 The word ―big‖ in bigdata is not just about the volume. Its also about the
3v`s.
 They are;
 Volume
 Velocity
 Variety.

5. ATTRIBUTES OF BIGDATA :
 Volume – is that huge amount of digital data created by all sources –
companies, individuals and devices. (What constitutes ―big‖ varies by
perspective and will certainly change over time.)
 Velocity – is the speed of creation, which in turn drives interest in real-time
analytics and automated decision-making.
 Variety - comes from increasing types of data – some structured, as in
databases, much of it unstructured text or video and some semi-structured
data like social media data, location-based data, and log-file data.

6. EXAMPLES OF BIGDATA
 Sensor networks
 Social networks
 Internet search index
 Astronomy
 Internet text and documents
 Large scale e-commerce
 Weblogs and video archives
 Medical records and call detail records ,etc.

7. SIZE OF BIGDATA?
 Google :
24PB data processed daily.
 Facebook:
750 million users
12TB daily content
2.7 billion ―likes‖ and ―comments‖.
 Twitter:
340 million daily tweets
1.6 billion search queries
7TB added daily.

8. BIGDATA LANDSCAPE:

9. INDUSTRIES THAT ARE USING BIGDATA:
 Banking
 Risk & Fraudulent management
 Customer Analytics
 Telecommunications
 Call detail record processing
 Customer profile
 Health care
 Medical Record text analytics
 Genomic Analysis
 Digital Media
 Real-time ad targeting
 Website analysis
 Government
 Abuse & Fraudulent management
 Customer Analytics

10. TECHNOLOGY:
 Bigdata is Driven mainly by Open Source Initiatives such as :
 Apache TM HADOOP Project
 Apache TM CASSANDRA Project
 Apache TM HBASE Project
 Apache TM HIVE Project
 Apache TM SOLR Project

11. HADOOP :
 What is Hadoop?
 Flexible infrastructure for
large scale computation
and data processing on
a network of commodity
hardware.
 Hadoop is completely
written using JAVA.
 Hadoop is an open
source and it is
distributed under Apache
license,
 Hadoop is not :
 a file system nor a
database.
 Not a replacement for
exciting data warehouse
systems nor for all
programing logics.
 Not an On Line
Transaction Processing
(OLTP) system.

12. WHEN SHOULD WE GO FOR HADOOP?
 When the data is too huge
 When the processes are independent
 For online analytical processing (OLAP)
 For a better scalability
 For Unstructured data
 Also for Parallelism

13. --BACK TO BIGDATA—
ADVANTAGES:
 Largest and fast growing market
 Leaveraging bigdata for insights can enhance productivity and
competitiveness for companies
 Harnessing bigdata will enable business to improve market intelligence
 Latest trend for IT Professionals in the area of data analytics

14. RISKS OF BIGDATA:
 Will b so overwhelmed
 Need the right people and solve the right problem
 Technological considerations
 Open source
 Scalability and performance issue
 Many source of bigdata is privacy
 Self regulation
 Legal regulation
