The answer is more complicated for SQLite: https://sqlite.org/isolation.html

> There can only be a single writer at a time to an SQLite database. There can be multiple database connections open at the same time, and all of those database connections can write to the database file, but they have to take turns.

However, it can also be configured in WAL mode where the single writer is applying WALs while the applications append to the log.

I can use my Macbook's microphone while my hifi system is blasting death metal at full volume. The people I'm talking to can't hear the music at all and still hear me perfectly. (The Macbook has multiple microphones in an array which can isolate the speaker from the surroundings.)
