>A cloned database view is some representation of your database that has been post-processed to only contain data that the user is allowed to see. This representation would typically be in the form of a separate user-specific sqlite database file. Because the cloned database only contains data that is theirs, a user may issue any query against it, and there is no risk to data security. And if a malicious user was able to issue a DDL statement, it would only affect their cloned database.

Maybe there is a better word than "cloned database view." Replica doesn't feel quite right though.
