The DB-WAL is a temporary database file created by SQLite 3.7.0 or later, commonly embedded into mobile and desktop applications. It saves write-ahead log information for the database, and is automatically created and managed by the database. 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.
