extends abstract class Phalcon\Di\Injectable
implements Phalcon\Events\EventsAwareInterface, Phalcon\Di\InjectionAwareInterface, Phalcon\Mvc\Model\Transaction\ManagerInterface
A transaction acts on a single database connection. If you have multiple class-specific databases, the transaction will not protect interaction among them. This class manages the objects that compose a transaction. A trasaction produces a unique connection that is passed to every object part of the transaction.
