Inspired by Ruby on Rails' migrations, migrate provides a way to deal with database schema changes in SQLAlchemy projects. . SQLAlchemy-migrate is build on top of SQLAlchemy and provides a changeset and a versioning API for database schemas as well as a script utilizing these APIs. The database change sets are managed in a file based repository allowing upgrades and downgrades of database schema versions. The change sets may consist of Python code facilitating the changeset API or SQL scripts. . SQLAlchemy-migrate has support for MySQL, PostgreSQL, SQLite and Oracle databases. The support for Oracle is not as well tested as the support for the other database systems.
