 h3. Object Relational Mapping
 
-The relation between databases and object-oriented software is called ORM, which is short for "Object Relational Mapping". The purpose of an ORM framework is to minimize the mismatch existent between relational databases and object-oriented software. In applications with a domain model, we have objects that represent both the state of the system and the behaviour of the real world elements that were modeled through these objects. Since we need to store the system's state somehow, we can use relational databases, which are proven to be an excelent approach to data management. Usually this may become a very hard thing to do, since we need to create an object-oriented model of everything that lives in the database, from simple columns to complicated relations between different tables. Doing this kind of thing by hand is a tedious and error prone job. This is where an ORM framework comes in.

 h3. Active Record inside the MVC model
 
-Active Record plays the role of model inside the MVC structure followed by Rails applications. Since model objects should encapsulate both state and logic of your applications, it's ActiveRecord responsability to deliver you the easiest possible way to recover this data from the database.

 h3. Convention over Configuration in ActiveRecord
 
-When writing applications using other programming languages or frameworks, it may be necessary to write a lot of configuration code. This is particulary true for ORM frameworks in general. However, if you follow the conventions adopted by Rails, you'll need to write very little configuration (in some case no configuration at all) when creating ActiveRecord models. The idea is that if you configure your applications in the very same way most of the times then this should be the default way. In this cases, explicity configuration would be needed only in those cases where you can't follow the conventions for any reason.

 ActiveRecord 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 table_id i.e. (item_id, order_id). These are the fields that ActiveRecord will look for when you create associations between your models.
-* *Primary keys* - By default, ActiveRecord will use a integer column named "id" as the table's primary key. When using "Rails Migrations":http://guides.rails.info/migrations.html to create your tables, this column will be automaticaly created.

 h3. Validations
 
-ActiveRecord gives the hability to validate the state of your models before they get recorded into the database. There are several methods that you can use to hook into the lifecycle of your models and validate that an attribute value is not empty or follow a specific format and so on. You can learn more about validations in the "Active Record Validations and Callbacks guide":http://guides.rails.info/activerecord_validations_callbacks.html#_overview_of_activerecord_validation.

 h3. Callbacks
 
-ActiveRecord callbacks allow you to attach code to certain events in the lifecycle of your models. This way you can add behaviour 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":http://guides.rails.info/activerecord_validations_callbacks.html#_callbacks.
