An entity bean represents an entity such as an employer,
student, etc. A session bean is a type of EJB (Enterprise
JavaBean) that encapsulates the logic of a business process
and business rules. Entity beans offer the following
advantages over session beans:
Persistence: Entity beans are persistent, i.e., the state
of the bean exists beyond the lifetime of the application
or the application process. There are two types of
persistence: Bean-managed and Container-managed. In Bean-
managed persistence, the code contains the calls that
access the database. In Container-managed persistence, the
EJB container generates the database calls.
Shared Access: Multiple clients can share the entity beans.
It works within the transactions as the client changes the
data.
Primary Key: Each entity bean has a unique object
identifier that enables the client to locate a particular
entity bean.
Relationship: An entity bean can relate to other entity
beans. Both CMP and BMP can be used to maintain
relationships.
