Why puchikarui

puchikarui is a tiny, 100% pure-Python library that provides extra functionality to Python 3's sqlite3 module. It helps working directly with sqlite3 easier, with less magic, and more control, rather than hiding sqlite3 module away from the users.

Although puchikarui does provide some ORM-like features, it is NOT an ORM library. If you want ORM features, please consider PonyORM, SQLAlchemy, or peewee.

Meaning

The name puchikarui came from two Japanese words プチ (puchi) which means small, and 軽い (karui), which means light, soft, and gentle.

It represents the motivation for developing this library: a tiny, lightweight library that makes working with sqlite3 simpler.
