APSW is a Python wrapper for the SQLite embedded relational database engine. In contrast to other wrappers such as pysqlite it focuses on being a minimal layer over SQLite attempting just to translate the complete SQLite API into Python.

An SQL to OO mapper with an object API inspired by Class::DBI (with a compatibility layer as a springboard for porting) and a resultset API that allows abstract encapsulation of database operations. It aims to make representing queries in your code as perl-ish as possible while still providing access to as many of the capabilities of the database as possible, including retrieving related records from multiple tables in a single query, "JOIN", "LEFT JOIN", "COUNT", "DISTINCT", "GROUP BY", "ORDER BY" and "HAVING" support.
