Enterprise Java Beans (EJB)

Enterprise Java Beans (EJB) are server-side components used in Java-based applications to handle complex business logic, transactions, and security. They simplify the development of large-scale, distributed applications by providing a structured environment where developers can focus on core functionality. EJB manages important tasks like database interactions, user authentication, and transaction control automatically, ensuring reliability and scalability. Essentially, EJB acts as a middleware layer that streamlines building and maintaining robust, enterprise-level software systems, allowing developers to concentrate on application-specific features while relying on the container to manage common, repetitive tasks.
