In general, "live data" means actual data in real-world usage (e.g. actual customer data, sales records, inventory entries, etc.) as opposed to "test data", used for testing (which is often just a copy of live data). If you're working with live data, you affect actual probably-important company data, whereas if you're working with test data, goofs don't matter nearly as much.

The "online" part probably just means that it's visible over the internet in some way, whether it's to developers, customers, internally, or whatever.

✔ Best Answer
I'd say that "live" means working with data in real time, as it
is acquired, so that a response can be given immediately.
As opposed to working with data which has been recorded
and stored for later analysis. Interactive vs batch.

Like the difference between a firefighter who has to respond
to a fire while the fire is burning, and an investigator who can
take time to collect and analyze all the evidence to determine
what caused it.
