The main runtime interface between a Java application and Hibernate. This is the central API class abstracting the notion of a persistence service.
  The lifecycle of a Session is bounded by the beginning and end of a logical transaction. (Long transactions might span several database transactions.)
  The main function of the Session is to offer create, read and delete operations for instances of mapped entity classes.  <\/p><\/blockquote>\n
