What is Database?
A persistent store of structured data; a query is the request you send to read or change it.
query: active → 3 of 12 rows
In real work
Confirm the query the agent wrote filters the right rows before QA signs off.
In the illustration
A query tag sets the hole for 'active'; the needle slides through the deck, lifts, and 3 of the 12 cards drop free while the rest stay stored in the drawer.
Write the query in your coding agent that pulls last week's orders from the database, and explain each clause in one line.
