Rollback: remove a patch/revision from history Cherry-picking : move only some revisions from a branch to another one (instead of merging the branches) Bisect : binary search of source history for a change that introduced or fixed a regression
A schema migration is performed on a database whenever it is necessary to update or revert that database's schema to some newer or older version.
