python39-alembic - Database migration tool for SQLAlchemy
- Description:
Alembic is a database migrations tool written by the author of
SQLAlchemy. A migrations tool offers the following functionality:
• Can emit ALTER statements to a database in order to change the
structure of tables and other constructs
• Provides a system whereby "migration scripts" may be constructed;
each script indicates a particular series of steps that can
"upgrade" a target database to a new version, and optionally a
series of steps that can "downgrade" similarly, doing the same steps
in reverse.
• Allows the scripts to execute in some sequential manner.
Documentation and status of Alembic is at:
