Due to the server-less design, SQLite applications require less configuration than client–server databases. SQLite is called "zero-conf" because it does not require service management (such as startup scripts) or access control based on GRANT and passwords. Access control is handled by means of file-system permissions given to the database file itself. Databases in client–server systems use file-system permissions that give access to the database files only to the daemon process.
