## What it is
greenDAO is a lightweight, high-performance ORM for Android that maps Java objects to SQLite databases with a simple annotation-based API. The project is no longer actively maintained, with greenrobot recommending its successor ObjectBox for new apps.

## Use cases
- persist Java objects to SQLite on Android without writing SQL
- run fast queries with joins across entities via QueryBuilder
- encrypt the local app database with SQLCipher
- map custom classes or enums to database columns
- migrate an existing greenDAO app to ObjectBox via DaoCompat

## When to choose
- maintaining a legacy Android app already built on greenDAO
- you need a tiny (<150KB), pure-Java ORM for Android SQLite
- you want SQLCipher-encrypted local storage with an ORM API

## When to avoid
- starting a new Android project - use ObjectBox, Room, or SQLDelight instead
- you need ongoing updates, bug fixes, or modern Android/Kotlin support
- you need a database beyond SQLite on non-Android platforms

## Facets
- artifact type: library
- maturity: abandoned
- function: orm, database, database-driver
- domain: databases, mobile-development, android-tools
- platform: jvm
- tags: sqlite, android-orm, sqlcipher, code-generation, gradle-plugin, not-maintained, android
