1 Alembic is a new database migrations tool, written by the author of
2 SQLAlchemy. A migrations tool offers the following functionality:
4 - Can emit ALTER statements to a database in order to change the structure of
5 tables and other constructs
6 - Provides a system whereby "migration scripts" may be constructed; each
7 script indicates a particular series of steps that can "upgrade" a target
8 database to a new version, and optionally a series of steps that can
9 "downgrade" similarly, doing the same steps in reverse.
10 - Allows the scripts to execute in some sequential manner.
