# Class Phalcon\\Mvc\\Model\\Manager # Class **Phalcon\\Mvc\\Model\\Manager** *implements*[*Phalcon\\Mvc\\Model\\ManagerInterface*](#), `Phalcon\Di\InjectionAwareInterface`, [*Phalcon\\Events\\EventsAwareInterface*](#) This components controls the initialization of models, keeping record of relations between the different models of the application.
