The document discusses the 5 V's of big data: Volume, Velocity, Variety, Veracity, and Value. Volume refers to the vast amounts of data generated every second from sources like social media and sensors. Velocity is the speed at which new data is created, such as credit card transactions. Variety means the different types of data including structured, unstructured, and semi-structured. Veracity addresses the uncertainty in data quality. Value ensures the large amounts of data can be analyzed and applied to business cases.

1. BIG DATA 5 V’s/Characteristics
Big data refer to massive data collected from
variety of operational sources for business
Need to reveal optimize decision making in
business context.

2. ● E-business and social media create 2.5 Exabytes of data per day.
● Data is store for analysis,to reveal hidden correlation and pattern.

3. 5 V’s
Characteristics of V .
➔ Volume.
➔ Velocity
➔ Variety
➔ Veracity
➔ Value

4. ● Refer to the vast amount of data generated every second.
● Data generated from emails,social networking sites,photos,videos,sensor
data etc.
● Data Generated is in zettabytes.
● This increasing data sets too large to store and analysis
using traditional database.
● Now with big data Technology we can store and use
dataset with help of distributed system. Volume

5. ● Refer to the speed at which new data is generated.
● Example the speed at which credit card transaction are checked for
detecting the fraudulent activities.
● Big data technology allow us to analysis the data without
ever putting into database.
Velocity

6. ● Refer to the different type of data we can use.
● In past we use to deal with only structure data which nearly fits in the
structure table databases like MYSQL.
● Now 80% of the data is unstructured and cant be put in table easily .
● With big data we can handle not only structure data but
also accomodate unstructured data and semi-structure
data .
Variety

7. ● Refer to the uncertainty of data.
● Data is present in many form so the quality and accuracy is less
controllable.
● But Big data allow us to do handle the uncertainty in huge
amount of data produced
Veracity

8. ● Most important V.
● It ensure that huge data is available in the business context.
● Collect the big data analysis it and make it available in the test cases
required for business.
Value

9. ● Refer to the vast amount of data generated every second.
● Data generated from emails,social networking sites,photos,videos,sensor
data etc.
● Data Generated is in zettabytes.
● This increasing data sets too large to store and analysis
using traditional database.
● Now with big data Technology we can store and use
dataset with help of distributed system. Volume
