How much data is Big Data?

How much data is Big Data?
◎ Byte is a unit of measure of digital
information.
◎ Terabyte is the starting flag to participate in
the Big Data race.

Big Data Types
![Page 14: Big data (Data Size doesn't Matter, How and What is Data that's matter)](https://reader035.vdocuments.net/reader035/viewer/2022081520/587892fd1a28ab375f8b60d7/html5/thumbnails/14.jpg)
Big Data Types
◎ Structured Data indicate information which is well organized.
◎ Semi-Structured Data lacks the strict data model structure.
◎ Unstructured Data lacks structure in formation.

Sources of Data

Sources of Data
◎ Human Generated Data
◎ Machine Generated Data
◎ Social Graph Generated Data

Stages to Big Data
![Page 18: Big data (Data Size doesn't Matter, How and What is Data that's matter)](https://reader035.vdocuments.net/reader035/viewer/2022081520/587892fd1a28ab375f8b60d7/html5/thumbnails/18.jpg)
Stages to Big Data
◎ Data Acquisition Acquire the Data.
◎ Data Extraction All generated and acquired data is not of use.
◎ Data Collation Data from singular source often is not enough for
analysis or prediction.
More than one data sources are combined to give big
picture to analyze.
![Page 19: Big data (Data Size doesn't Matter, How and What is Data that's matter)](https://reader035.vdocuments.net/reader035/viewer/2022081520/587892fd1a28ab375f8b60d7/html5/thumbnails/19.jpg)
Stages to Big Data
◎ Data Structuring Store acquired data in structure format.
◎ Data Visualization Data analysis involves targeting areas of interest and
providing result based on the structured data.
◎ Data Interpretation The ultimate step as Data Processing.
