Data modelling - Concept
Transactional data
Records created by day-to-day business events such as purchases, payments, bookings or shipments
What's it for?
Records real business events such as purchases, payments and bookings so organisations know what actually happened.
For example…
Each card payment creates a transaction row with time, amount, and merchant details
Each purchase, refund and payment creates transactional data recording what happened, when it happened and which customer or order it concerned
Think of it like…
Till receipts and bank entries—the day-to-day trail of what was bought and sold
