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 the 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.
|
|
|
|
Active Record relies heavily on naming in that it uses class and association
|
|
names to establish mappings between respective database tables and foreign key
|
|
columns. Although these mappings can be defined explicitly, it's recommended to
|
|
follow naming conventions, especially when getting started with the library.
