I want to learn about the types of big data.
It would be clear to divide the types based on data size, so I marked them based on size.

Structured data refers to text-oriented data. And semi-structured and unstructured data are being generated in large quantities.
In terms of data size, MB and GB are the size of structured data, TB is semi-structured data, and PB is the size of big data.

 

Structured data vs unstructured data

 

Standardized data
Business system data such as management system, information system, analysis system, etc.

* Data size: MB, GB

- Financial information, payroll, personnel information
- Inventory management, transaction information, customer information

 

Semi-structured data
A form of structured data that does not conform to the structured data model

* Data size: TB

- Various other device data
- Web Log data
- Security and specific sensor data
- Marketing information

 

Data classification

 

Big data

Data format with unstructured form or structure All data in various formats
* Data size: PB

- Document, text, image, video, social data
- Sensor (Sencor) data device log data
- Virtual data RFID data
-SNS data
-Including data in various other formats


Although big data encompasses all data,
It can be called big data when the size and type of data are diverse.
