Lightweight persistence library for Android. It simplifies work with SQLite database by providing high level APIs which allows to perform CRUD operations directly with Java classes. The big benefits of this library is its ability to persist Java objects without writing a boilerplate code for mapping between Java and SQL.

GreenDAO is an open source project to help Android developers working with data stored in SQLite. Models can be generated using a handy DSL. The generated code is much faster than ORMs that use annotations. Good examples are included.

Object Relational Mapping Lite (ORM Lite) provides some lightweight functionality for persisting Java objects to SQL databases while avoiding the complexity and overhead of more standard ORM packages.
