Data modelling - Concept
Structured data
Data organised into consistent, predefined fields and rows
What's it for?
Makes information easy to sort, filter and compare because it follows a clear, consistent structure.
For example…
An employee list with name, start date, and department columns is structured data
A customer table with fixed columns for CustomerID, name, email and status is structured data that can be filtered and joined easily
Think of it like…
Spreadsheet with labelled headers rather than a pile of handwritten notes
