BIG DATA

Many of us wondering what does big data does and why it is necessary in our life.most of all all why we

we need it where it is used here is the detailed description of it.

A big data analysis is a data set which is very complex and are the data processing application software.

It includes capturing data, data storage,data analysis,visualization,querying.

 

What is Big Data?

Big data encompasses unstructured,semi-structured and structured data.

The main focus of big data is on unstructured data.

Big data represents the information about  high volume, velocity and variety for require specific

technology and analytics methods.

 

TOOLS OF BIG DATA:

The tools which are required for big data analytics are:

1 Apache Hadoop

2 Microsoft HDInsight

3 No sql

4 Hive

5 Sqoop

6 Poly base

7 Presto

8 BigData in excel.

APPLICATIONS:

There are many application of BIG DATA :

some of them are->

Internet of things: Big data and the IoT work in conjunction. Data extracted from IoT devices

provides a mapping of device inter connectivity.

Sports:

Big data can be used to improve training and understanding competitors, using sport sensors.

Sampling big data:

Sampling (statistics) enables the selection of right data points from within the larger data set to

estimate the characteristics of the whole population.

 

DRAWBACKS:

Prioritizing correlations:

Data analysts use big data to tease out correlation: when one variable is linked to another.

However, not all these correlations are substantial or meaningful.

SECURITY:

As with many technological endeavors, big data analytics is prone to data breach. The information that you provide a third party could get leaked to customers or competitors.
