Rose::DB::Object is a base class for objects that encapsulate a single row in a database table. It provides the following functions: * Create a row in the database by saving a newly constructed object. * Initialize an object by loading a row from the database. * Update a row by saving a modified object back to the database. * Delete a row from the database. * Fetch an object referred to by a foreign key in the current object. (i.e., "one to one" and "many to one" relationships.) * Fetch multiple objects that refer to the current object, either directly through foreign keys or indirectly through a mapping table. (i.e., "one to many" and "many to many" relationships.) * Load an object along with "foreign objects" that are related through any of the supported relationship types.
