Message Driven Beans

Message Driven Beans (MDBs) are components in Java EE that enable applications to handle asynchronous messages from sources like message queues or topics. Think of them as in-plant couriers that listen for incoming messages and process them automatically when received, without ongoing manual intervention. This setup allows systems to efficiently manage and respond to large volumes of messages or tasks in the background, enhancing scalability and responsiveness. MDBs are commonly used in enterprise applications for tasks such as processing orders, notifications, or data updates, enabling decoupled and flexible communication within complex software systems.
