Alembic is a new database migration tool, written by the author
of SQLAlchemy. A migration 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.
