Using SQLite

The document provides an overview of SQLitePersistentObjects (SQLPO), an object-relational mapping (ORM) tool for SQLite databases on iPhone. It discusses how to define persistent objects that map to database tables, and perform common CRUD operations like saving, finding, and deleting objects. SQLPO handles mapping data types to columns and storing relationships and collections. It also supports custom queries, indices, and other features to improve performance and flexibility.
