Data flow - Format
XML
A text format that organises data using named labels inside one another
What's it for?
Gives systems a labelled text format for exchanging structured information.
For example…
A supplier sends nightly stock updates in an XML file.
A supplier sends an order file where each item is wrapped in named labels so the receiving system knows what each value means
Think of it like…
Packing labelled boxes of goods inside larger labelled boxes to keep everything organised
