module Sequel
# <tt>Sequel::Model</tt> is an object relational mapper built on top of Sequel core. Each
# model class is backed by a dataset instance, and many dataset methods can be
# called directly on the class. Model datasets return rows as model instances,
# which are wrappers around the underlying hash that allow easily updating or
# deleting the individual row.
#
# <tt>Sequel::Model</tt> is built completely out of plugins. Plugins can override any class,
# instance, or dataset method defined by a previous plugin and call super to get the default
# behavior. By default, <tt>Sequel::Model</tt> loads two plugins, <tt>Sequel::Model</tt>
# (which is itself a plugin) for the base support, and <tt>Sequel::Model::Associations</tt>
# for the associations support.
#
# You can set the +SEQUEL_NO_ASSOCIATIONS+ constant or environment variable to
# make Sequel not load the associations plugin by default.

# Just like any other method defined by Sequel, if you override one of these, you should

# by plugins). See the {"Model Hooks" guide}[rdoc-ref:doc/model_hooks.rdoc] for
