## What it is
A small Android library that simplifies greenDAO database schema upgrades to a single migrate() call, preserving data by recreating tables. It extends DaoMaster.OpenHelper and handles dropping and recreating all DAO tables during onUpgrade.

## Use cases
- upgrade greendao database schema without losing data
- migrate android sqlite database to new version
- handle greendao onUpgrade with one line of code
- recreate greendao tables during app database migration
- avoid writing manual database migration logic in android

## When to choose
- you use greenDAO and need simple schema upgrades that preserve data
- you want to avoid hand-writing ALTER TABLE migration logic
- your app's database schema changes between app versions

## When to avoid
- you use Room, ORMLite, or another ORM instead of greenDAO
- you need fine-grained column-level data migration rather than table recreation
- you need a library with an explicit license or active maintenance
