= Active Record -- Object-relational mapping put on rails Active Record connects classes to relational database tables to establish an almost zero-configuration persistence layer for applications. The library provides a base class that, when subclassed, sets up a mapping between the new class and an existing table in the database. In context of an application, these classes are commonly referred to as *models*. Models can also be connected to other models; this is done by defining *associations*. (This is part of Ruby on Rails 3.)
