软件包: alembic (1.7.6-1)

lightweight database migration tool for SQLAlchemy

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.

This package provides /usr/bin/alembic script and documentation for Alembic, and depends on the python3-alembic package which contains all the actual code (in Python 3) for Alembic to actually work.
