Answer / janet
There are two types of Enterprise beans- session beans and
entity beans representing different types of business logic
abstractions.
session beans represent behaviors associated with client
sessions ,they are generally implemented to perform a
sequence of tasks with in the context of a transaction. A
session bean is a logical extension of the client program
,running process on the clients behalf remotely on the server.
Entity bean represent specific data or collection of data
,such as a row in a relational database.Entity bean methods
provided operations for action on the data represented by
the bean.An entity bean is persistent,it servives as long as
its data remains in the database.
