Structured data resides in predefined formats and models, Unstructured data is stored in its natural format until it’s extracted for analysis, and Semi-structured data basically is a mix of both structured and unstructured data.

What is the main function of structured and unstructured data?

Structured data is used in machine learning and drives machine learning algorithms. Unstructured data is used in natural language processing and text mining. Structured data is stored in tabular formats like excel sheets or SQL databases.

What is semi structured data example?

Semi-Structured Data Examples An example of semi-structured data is delimited files. It contains elements that can break down the data into separate hierarchies.
