java Hibernate is a tool that performs the mapping between
oriented world object-world applications and
entity-relationship databases in Java environments. The term used is
ORM (object / relational mapping) and technology is making the transition
a representation of the data in a relational model
an object-oriented model and vice versa. Hibernate
not only does this this transformation but provides capabilities for collecting and storing data from the database that we reduce development time.
the structure of this framework we can see in an article in my blog:

the framework.
4 .- let's create the objects related to the data base we select
5 .- now generate the hbm.xml of each table is related to an object of type beans
5.1 Although we have the draft 
6 .- generate the kind newhibernateUtil
