EJB (Enterprise JavaBeans)

Enterprise JavaBeans (EJB) are components used in Java-based server applications to handle complex tasks like processing transactions, managing data, and ensuring security. They enable developers to build scalable, reliable, and maintainable business logic independently of the application's user interface. EJBs run on a server and provide standardized services such as connection pooling and transaction management, allowing developers to focus on core functionality. Overall, EJBs simplify the development of enterprise-level applications by offering reusable, secure, and robust components that can be easily managed and integrated.
