      Variety of Data

     

 

• Big Data is inclusive of the forms of data for all kinds

of functions and from all sources and devices . If

traditional data forms such as invoices and ledgers

were like a small store then Big data can be considered

as the biggest imaginable shopping mall that offers

unlimited variety .

 

• The three major kinds of variety of data are as follows :

 

01) FORM OF DATA :

Data types range in variety from numbers to text ,

graph , map , audio , video and many other forms with

some of the data types being simple and the othes

being very complex . There can be composites of

data that include many elements in a single file . For

example , text documents have graphs and pictures

embedded in them . Video movies have audio songs

embedded in them . Audio and Video have different

and vastly much complex storage formats than

numbers and text .Numbers and text can be more

easily analysed than audio or video file

 

02) FUNCTIONS OF DATA :

There is a lot of data that is being generated form human conversations , songs and movies , business transactions records , machine operations performance data and anew

product design data , old archived data , etc . Human

communication data is needed to be processed very

communication data is needed to be processed very

much differently form operational performance data

with different expectations and objectives . Because

of all these aspects , Big data technologies can be

used to recognise people's faces in ictures , compare

voices to identify speaker of the voice and compare

handwritings to identify the writer also .

 

03) SOURCE OF DATA :

Mobile phones and tablet devices enable a wide series of applications ( or apps ) to access data and also generate data from anytime and anywhere . Web access and usage and search logs are another new and huge source of data . Businesses and enterprise systems generate massive amounts of structured business transactional information .Temperature and pressure sensors on machines , and Radio Frequency (RFID) tags on assets , generate incessant and repetitive data .

 

 

Overall it can summarised as there are three forms of

data and data sources :

(i) human - human communications

(ii) human -machine communications

(iii) machine to machine communications
