Big Data & Hadoop Training in noida



Hadoop is an open-source framework that allows to store and process big data in
A distributed environment across clusters of computers using simple
Programming models. It is designed to scale up from single servers to thousands
Of machines, each offering local computation and storage.
This brief tutorial provides a quick introduction to Big Data, Map Reduce
Algorithm, and Hadoop Distributed File System.
Big Data is a collection of large datasets that cannot be processed using
traditional computing techniques. It is not a single technique or a tool, rather it
               involves many areas of business and technology.


 What Comes Under Big Data?
Big data involves the data produced by different devices and applications. Given
Below are some of the fields that come under the umbrella of Big Data.
 Black Box Data: It is a component of helicopter, airplanes, and jets, etc.
It captures voices of the flight crew, recordings of microphones and
Earphones and the performance information of the aircraft.
 Social Media Data: Social media such as Facebook and Twitter hold
Information and the views posted by millions of people across the globe.
 Stock Exchange Data: The stock exchange data holds information about
the ‘buy’ and ‘sell’ decisions made on a share of different companies made
by the customers.
 Power Grid Data: The power grid data holds information consumed by a
Particular node with respect to a base station.
 Transport Data: Transport data includes model, capacity, distance and
Availability of a vehicle.
 Search Engine Data: Search engines retrieve lots of data from different
Databases.
Thus Big Data includes huge volume, high velocity, and extensible variety of
Data. The data in it will be of three types.
 Structured data: Relational data.
 Semi Structured data: XML data.
 Unstructured data: Word, PDF, Text, Media Logs.
Benefits of Big Data
 Using the information kept in the social network like Facebook, the
Marketing agencies are learning about the response for their campaigns,
Promotions and other advertising mediums.
 using the information in the social media like preferences and product
Perception of their consumers, product companies and retail organizations
Are planning their production.
 using the data regarding the previous medical history of patients,
                Hospitals are providing better and quick service.
