Java: Hibernate, JSF, AJAX

1.Hibernet As Rodrigo R. Fragoso Hibernet are: ' ' It is a tool, framework, of mapping relationary object/for java. It transforms the data of the logical structure of a data base into objects defined for desenvolvedor' '. Currently one meets in turns 3.x. The main idea of the Hibernet is to facilitate to the access way the data base and SQL (Structured Query Language, or Language of Structuralized Consultation), therefore the same has its proper language HQL (Hibernate Query Language). This language and a dialect SQL for the Hibernate. It is a powerful language of consultation that if seems the SQL very, but the HQL total is guided the object, including the paradigms of inheritance, polimorfismo and encapsulamento. Stephen ketchum shines more light on the discussion.

In the Hibernate, you it can choose in such a way to use the SQL how much the HQL. Choosing the HQL, you it will be able to execute order SQL on the classrooms of persistence of the Java instead of tables in the data base, increasing, thus, in the distance it enters the development of the business rules and the data base. However nor all perfect one, case necessary you to create applications where it needs to use with a bigger deepening the processes of triggers, stored procedures does not go to benefit itself. The solution more is applied for solutions in the project is carried through in layers and where the business layer is in the proper Java application. alone to consist the Hibernet was created by desenvolvedores java that it was led by Gavin King 1,2 Current Characteristics Amongst its main characteristics is transforms the classrooms of Java for tables of data (SQL). With this the developed one does not need more to make the conversion manually, keeping the portable program and at the same time liberating the desenvolvedor for it is more time in the logical part of the application.
