Rails provides migrations to help you evolve your database schema in a convenient way. In your new Rails application, your database schema starts off empty. Active Record helps you update it whenever a new migration is run.Why do you need migrations?The majority of web applications need a database. A database is used for storing the data of the web application. Typically you would run SQL statements to create or modify your database.Rails introduces a domain specific language for writing database instructions. This saves you from writing SQL statements.
