Unlike other similar libraries Og maps standard Ruby objects to SQL tables and not vice versa. Og provides a meta language to describe the relations between objects, a flexible and intuitive api for querieng the database, raw access to the SQL language if needed (for example to fine tune the automatically generated SQL tables, or for custom queries), suports deserialization to Ruby objects or tuples, automatically generates join tables for many_to_many relations and provides a collection of usefull Mixins to synthesize common Entities.
