 What is Active Record?

 Active Record uses naming conventions for the columns in database tables, depending on the purpose of these columns.
 
 * *Foreign keys* - These fields should be named following the pattern `singularized_table_name_id` (e.g., `item_id`, `order_id`). These are the fields that Active Record will look for when you create associations between your models.
-* *Primary keys* - By default, Active Record will use an integer column named `id` as the table's primary key. When using "Rails Migrations":migrations.html to create your tables, this column will be automatically created.

+* `type` - Specifies that the model uses [Single Table Inheritance](http://api.rubyonrails.org/classes/ActiveRecord/Base.html)
 * `(table_name)_count` - Used to cache the number of belonging objects on associations. For example, a `comments_count` column in a `Post` class that has many instances of `Comment` will cache the number of existent comments for each post.
 
 NOTE: While these column names are optional, they are in fact reserved by Active Record. Steer clear of reserved keywords unless you want the extra functionality. For example, `type` is a reserved keyword used to designate a table using Single Table Inheritance (STI). If you are not using STI, try an analogous keyword like "context", that may still accurately describe the data you are modeling.

 Validations
 -----------
 
-Active Record allows you to validate the state of a model before it gets written into the database. There are several methods that you can use to check your models and validate that an attribute value is not empty, is unique and not already in the database, follows a specific format and many more. You can learn more about validations in the "Active Record Validations and Callbacks guide":active_record_validations_callbacks.html#validations-overview.

 Callbacks
 ---------
 
-Active Record callbacks allow you to attach code to certain events in the life-cycle of your models. This enables you to add behavior to your models by transparently executing code when those events occur, like when you create a new record, update it, destroy it and so on. You can learn more about callbacks in the "Active Record Validations and Callbacks guide":active_record_validations_callbacks.html#callbacks-overview.

 Migrations
 ----------
 
-Rails provides a domain-specific language for managing a database schema called migrations. Migrations are stored in files which are executed against any database that Active Record support using rake. Rails keeps track of which files have been committed to the database and provides rollback features. You can learn more about migrations in the "Active Record Migrations guide":migrations.html
