Enterprise JavaBeans

Enterprise JavaBeans (EJB) are reusable software components used in Java-based applications to handle complex, server-side tasks such as processing transactions, managing data, and enforcing security. They run on a server, allowing developers to focus on business logic without worrying about underlying infrastructure. EJB provides a standardized way to build scalable, secure, and transactional applications, commonly used in enterprise-level systems like banking or e-commerce. Think of EJB as a toolkit that simplifies creating reliable, high-performance business applications by managing common functions behind the scenes.
