Since SQLite is a popular embedded database technology, you may see DB-WAL, .DB-SHM, and other temporary database files with applications that use SQLite.
注: In an SQLite write-ahead logging scheme, all database modifications are written to the DB-WAL file before being committed to the database. WAL was introduced as an alternative scheme to SQLite's default "rollback journal" policy.
