SQL
Structured Query Language
A language used to query and manage data in relational databases.
Example

Why it matters
It gives people and applications a precise way to ask questions of stored records.
You'll hear it
“Show the total for this period without changing the records.”
Can you control it?
Set by the team
The people building or running the AI choose this setup. An everyday user generally needs their help to change how this part works.
Common questions
- Can an SQL query modify data?
- Yes. Some commands add, update or delete information rather than just read it.
- Does valid SQL guarantee the intended answer?
- No. Wrong conditions or joins can produce a plausible but incorrect result.
- Can access be limited to reading?
- Yes. Permissions can restrict which commands and records a user may use.
