Does it mind that, if I had a two millions records table, I'll need a
lot of memory to support each instance of the entity bean ?

Hi Murali,
Session bean meant for your business process. It can do a simple thing like
tax calculation or connecting to another bean etc. The session beans are
verbs of your application. You cannot handle transaction management through
session bean. At the best you can get the data from the database but you
cannot do update existing record or adding a new record in the database.
The entity beans are nouns of your application. These are your persistence
objects. It represents your permanent data. Entity beans are capable of
handling the transactions. Each table in your database represents one entity
bean and each instance of a bean represents a record in that table.
You can use session beans for transaction but you have to go for
Synchronized session beans.
Regards,
Murthy
