An example of structured data is something stored in a clearly defined, tabular format such as a customer table in a database with fields like Name, Address, Phone Number, and Email. Structured data is organized in rows and columns with a fixed schema, which makes it easy for software and humans to search, sort, and analyze.

Quick Scoop: What counts as structured data?

Think of structured data as information that fits neatly into a spreadsheet- like grid.

  • It uses a predefined schema (set of fields and data types).
  • It is usually stored in tables with rows and columns.
  • It is easy to query using tools like SQL and to run reports and analytics.

Classic example:
A relational database table of customers:

  • Columns: CustomerID, Name, Address, PhoneNumber, Email.
  • Each row: one customer’s complete, consistently structured record.

This kind of database table is exactly what exam questions and interview questions usually mean when they ask: “Which of the following is an example of structured data?”
