Types of Data Under Big data

in this video we are going to discuss

types of data under Big Data so you know

that we are going to handle huge amount

of data under this big data and that's

why it has become a subject now we are

having mainly three category of data

will be coming here one will be our

structured data and the one is the

unstructured data and the last one will

be the semi structured data structure

determines that very data which can be

represented in the form of rows and

columns and that is known as the

structured data as an example we can say

that the respective web blocks the

different data which will be generated

by the sensors and say if we do any

survey on our population we'll be

getting our structured data structured

data is having the example of data base

in case of unstructured data the data

will be in the form of say data files

PDF images videos or the images sent by

the satellites and different machine

generated data or the videos could be

treated under the category of

unstructured data so that is also a huge

type structure deter now it is were

having 20 percent but unstructured data

is nowadays is having almost 80 percent

in case of semi structured data to some

extent it is structured to some extent

it is unstructured as an example we can

be discussing say XML files JSON files

and so on so they will be falling under

the category of semi structured data so

let us go for for the discussion on this

very topic the big data are categorized

into three different types that is a

structured data unstructured data and

semi structured data so let me discuss

each one of them one by one so at first

we are going for this database you can

find that this is a good example of a

structured data where having certain

columns so there is the employee number

name age department' and salary' and

here we are having their respective

roles containing the respective

information so here we are having the

records and here we are having the

columns so structured data are those

type of data which are stored already in

and order and there are nearly 20% of

the total existing data nowadays and

these data are structured and all the

data generated from sensors way blocks

and these all machine generated

structured data so these are the machine

generated structured data there is a way

blocks that is of a sensor data and so

on the human generated structured data

are those which are taken as information

from a human like their names addresses

gender and data part and so on so the

example of structured data is database

so now let us concentrate on the

unstructured data so these are

unstructured data so the unstructured

data have no clear format in storage and

we can store structured data in rows and

columns database but unstructured data

cannot be stored like that so

unstructured data cannot be stored in

the form of rows and columns and we are

having at least 80% of the data now it

is existing which is which are

unstructured all satellite generated

images scientific data or images are

categorized as a machine generated

unstructured data so the images which

will be sent by the respective

satellites can be treated falling in the

category of unstructured data there are

various types of human generated

unstructured data and these are the

images videos social media data etc so

the example of unstructured data are the

text documents PDFs images and videos

etc so this is the theory or this is a

concept against this unstructured data

so now let us come to the last category

that is the semi structured data so it

is very difficult to categorize this

type of data sometimes they'd look

structured and sometimes they will be

looking as unstructured so that's why

this data are known as semi structured

data we cannot store this type of data

using traditional database format and

but it contains some organizational

properties and examples of semi

structured data are spreadsheet files

which we have in our excel in our calc

we are having the spreadsheet files so

special sheet file is a good

Belov semi-structured data we're having

the xml or json documents there is a

Java Script object notation so extended

markup language there is a full form of

XML and no SQL database are the data

items which are falling under this

unstructured data so no skill is this is

one kind of database where we can keep

this type of data in a very efficient

way so in this video we have discussed

that what are the different types of

data that big data is going to handle
