* DbManager represents an authorization manager that stores authorization information in database.

* The database connection is specified by [[$db]]. The database schema could be initialized by applying migration:
*
* ```
* yii migrate --migrationPath=@yii/rbac/migrations/
* ```
*
* If you don't want to use migration and need SQL instead, files for all databases are in migrations directory.
*
* You may change the names of the three tables used to store the authorization data by setting [[\yii\rbac\DbManager::$itemTable]],
* [[\yii\rbac\DbManager::$itemChildTable]] and [[\yii\rbac\DbManager::$assignmentTable]].
