Today, we release greenDAO to the public. greenDAO is an ORM tool for Android that maps Java objects to SQLite database tables. It does that pretty quick and offers a nice and clean object oriented API for Android developers. With greenDAO, you write less SQL (or no SQL at all) and work directly with objects. During greenDAO’s development, we did not compromise on performance. We believe it’s the fastest ORM tool for Android around. Have a look at greenDAO’s features for more details.
