8.3.7. Manipulating a SQLite Database

The contact information is stored in a SQLite database. According to www.sqlite.org, SQLite is one of the world’s most widely deployed database engines. Each Fragment in this app interacts with a SQLite database via utility class DatabaseConnector (Section 8.9). That class uses a nested subclass of SQLiteOpenHelper (package android.database.sqlite), which simplifies creating the database and enables you to obtain a SQLiteDatabase object (package android.database.sqlite) for manipulating a database’s contents. Database queries are performed with Structured Query Language (SQL) and query results are managed via a Cursor (package android.database).
