= 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*.
