Full form of EJB
EJB stands for Enterprise Java Bean. It is a server-side, platform-independent Java API that provides a framework for developing distributed enterprise applications. EJBs are used to encapsulate business logic and provide services to other applications.
Types of EJBs
There are three types of EJBs:
- Entity beans: Entity beans represent persistent data in the database.
- Session beans: Session beans represent stateless business logic that is associated with a single user session.
- Message-driven beans: Message-driven beans process asynchronous messages.
Benefits of EJB
EJBs offer a number of benefits, including:
- Scalability: EJBs can be scaled to support large numbers of concurrent users.
- Portability: EJBs are portable across different Java platforms.
- Reliability: EJBs provide a number of features to ensure reliability, such as transaction management and failover.
- Security: EJBs provide a number of security features, such as role-based access control.
Where are EJBs used?
EJBs are used in a variety of enterprise applications, such as:
- E-commerce: EJBs can be used to implement the business logic for e-commerce applications, such as product catalogs, shopping carts, and payment processing.
- Enterprise resource planning (ERP): EJBs can be used to implement the business logic for ERP systems, such as financial management, human resources, and supply chain management.
- Customer relationship management (CRM): EJBs can be used to implement the business logic for CRM systems, such as sales force automation and customer support.
Overall, EJBs are a powerful tool for developing distributed enterprise applications. They offer a number of benefits, such as scalability, portability, reliability, and security.
