Overview

A library for storing schema-less data in a relational database, using ActiveRecord models and corresponding to a SQL-like API. Mixing in this module to your model will allow data to be stored as serialized hashes in your SQL tables, while being rendered as models in the application just like the rest of your data.

This also serves as the root module for the rest of the library. For more information on how this library works, see the other classes in this documentation.
