Introduction to Ruby on Rails

## What are migrations?
Migrations are a convenient way for you to alter your database in a structured and organized manner. They are a subclass of the `ActiveRecord::Migration` class. 

The `Migration` class in Active Record contains _helper methods_ that perform CRUD operations in a database-independent way. These helper methods include:
1. add/remove/_column
2. add/remove_index
3. change/rename_column
4. create/change/drop_table


These are the types of things we want our model class to be able to perform.
