OLTP — Online Transaction Processing

Definition: Databases optimized for high-volume, low-latency reads and writes of individual records. OLTP systems (Postgres, MySQL) power the application; OLAP systems power the reporting on top of it.

Example

In engineering planning, you'll often hear something like: "Let's pull the latest OLTP numbers before we make a call" — shorthand for online transaction processing.

When you'll hear it

OLTP shows up most often in engineering planning, architecture reviews, and sprint retrospectives. When someone uses it, they're usually referring to online transaction processing — and they expect the room to already know what that means.
