RailsMigrations.markdown

Basically how Rails knows how to form a database. Can be generated in two different ways

1. rails g migration name_using_underscores
   • Builds only the migration file, no models or tests
2. rails g model modelName
   • Builds model, migration file, and tests
   • Pass --skip-migration to bypass the migration and just create the model
3. Rails also knows and implements a clever way to deal with RailsSessions
4. RailsRunningMigrations
5. RailsMigrationAnatomy
6. RailsManagingTables
7. RailsAdvancedMigrations

###Best Practices

• If a migration has been pushed/commited, it's best not to modify it.
