What is OLTP (Online Transaction Processing)?
Database systems optimised for handling many small, fast transactions like user actions and purchases.
Why It Matters
OLTP databases power your application's day-to-day operations where speed and reliability matter most.
Real-World Example
A PostgreSQL database handling user registrations, orders, and payments in real time.
“Understanding terms like OLTP (Online Transaction Processing) matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
