A collection object is usually created by calling [[Database::getCollection()]] or [[Connection::getCollection()]]. Collection provides the basic interface for the Mongo queries, mostly: insert, update, delete operations. For example: php $collection = Yii::$app->mongodb->getCollection('customer'); $collection->insert(['name' => 'John Smith', 'status' => 1]); Collection also provides shortcut for Command methods, such as Collection::group, Collection::mapReduce and so on. To perform "find" queries, please use Query instead.
