What are structured, semi-structured, and unstructured data?

< 1 min read

Structured data is highly organized, like tables in a relational database with defined columns.
An example is customer records stored in a CRM system.
Semi-structured data has some structure but is more flexible, like JSON or XML files.
We used JSON API responses for system integrations in one project.
Unstructured data has no fixed format, such as emails or customer feedback text.
We analyzed survey comments to identify common customer issues.
Each data type requires different tools and handling approaches.
