Answer Posted / jadab
The SessionFactory is created from a Configuration object, and as its name implies it is a factory for Session objects.The SessionFactory is an expensive object to create. It, like the Configuration object, is usually created during application start up. However, unlike the Configuration object, It should be created once and kept for later use.The SessionFactory object is used by all the threads of an application. It is a thread safe object. One SessionFactory object is created per database. Multiple SessionFactory objects (each requiring a separate Configuration) are created when connecting to multiple databases. The SessionFactory can also provide caching of persistent objects.The main use of session factory object is to get the session object for the application.
