$model = Mage::getModel('example/model'); // create model object $model->setData('attribute_one', 'value_one'); $model->setData('attribute_two', 'value_two'); $model->save(); // save data to databaseIn this example, we first create a new instance of a model object using the `Mage::getModel()` method, passing in the model name as a string. We then use the `setData()` method to set the values of two attributes, and finally call the `save()` method to save these values to the database. The package library for this method is Magento's core library, as it is included within the `Mage_Core_Model_Abstract` class, which is a core class within the Magento framework.
