How does Ruby on Rails handle database migrations?

Ruby on Rails takes care of migrations. That allows it not only to keep the changes in the database schema directly but also provides this process with ease. As a matter of fact, migrations are tracked, and their different versions can be rolled back or consistently redeployed in various environments. This will ensure that all members working on a specific project have the same structure of the database and that itself will decrease the number of probable errors and facilitate the modification of the database schema.
