What is an SQLITEDB file?
A SQLITEDB file is a database file stored using SQLite, a database engine often used to create embedded SQL-based databases. It stores data using records, which contain data types and values. SQLITEDB files are most commonly used for storing contact information on iPhone devices.
The data within the iPhone contacts file AddressBook.sqlitedb can be viewed using SQLite Database Browser, an open-source program.
NOTE: SQLite database files also use the extension .SQLITE.
