Active Record Description

Object-relation mapping put on Rails Active Record ties database tables and classes together for business objects, like Customer or Subscription, that can find, save, and destroy themselves without resorting to manual SQL.Active Record connects business objects and database tables to create a persistable domain model where logic and data are presented in one wrapping. It's an implementation of the object-relational mapping (ORM) pattern.Active Record's main contribution to the pattern is to relieve the original of two stunting problems: inheritance and lack of associations. By adding a simple domain language-like set of macros to describe the former and integrating the Single Table Inheritance pattern for the latter, Active Record narrows the gap of functionality between the data mapper and active record approach.
