RE: What is session facade

Session facade is one design pattern that is often used while developing enterprise applications.
It is implemented as a higher level component (i.e.: Session EJB), and it contains all the iteractions between low level components (i.e.: Entity EJB). It then provides a single interface for the functionality of an application or part of it, and it decouples lower level components simplifying the design.
Basically we wrap all the calls inside a Session Bean, so the clients will have a single point to access (that is the session bean) that will take care of handling all the rest.
Hope this answers the question.
Thanks
