- Migration
- The contract of a versioned migration — one concrete subclass per
evolution, named `Version<timestamp>_<Label>` and stored in the host
project's migrations folder.
- MigrationAction
- The tracking document of a migration run — one row per applied version in
the `migrations` collection of a database.
- MigrationGenerator
- Generates a new migration file — the `migrate --create` boilerplate, with no
database dependency (it only writes a file).
- MigrationRunner
- The migration engine — discovers the version files, compares them with the
tracking collection of the database, and applies / rolls back the
difference.
- MigrationStore
- The persistence of the tracking collection — the bookkeeping half of the
migration engine.
