data => entity
synchronous service => session
asynchronous service => message

To me Customer sound as data.

hi thanks for the response.

can you please provide an example, what do you meant by "synchronise
service".

Say, a customer wants to deposit some cash.......is it a 'synchronise
service' .....is it a session bean ?

and also please explain 'asynchronous service 'by an example.

In this context:

synchronous = you call and wait for response while processing is done
asynchronous = you call and does not wait for processing to complete

To me deposit sound as synchronous.
