Datas' holding out for long time layer and Hibernate is one piece according to hold out for long time layer frame, is a kind of realization object and relation of the tool which reflect to shoot(O/R Mapping), it carried on the object of the lightweight to pack to the JDBC and make procedure member can usage object plait distance thought to operation database.It not only provided to shoot from Java to reflect of data form, but also provided a data a search and instauration mechanism.Opposite in usage JDBC and SQL to operation database, use a Hibernate ability consumedly of exaltation realization of efficiency.The Hibernate frame use allocation document of the form come to the reflect of the definition Java object and data form to shoot relation, in the meantime at more deep of level of data form of relation explanation for the relations such as inherit of and containment etc. of Java object.Pass the usage HQL language sentence complications of relation the calculate way use the way of object description, to a large extent simplification logarithms according to of search 更多：https://www.bmcx.com/ , speed development of efficiency.Have in the Hibernate a simple but keep the API of view, used for to the database mean of object performance search.Want to establish or the modification be these objects, need in the procedure carry on with them to hand over with each other, then tell Hibernate to keep.So, a great deal of pack hold out for long time turn operation of business logic no longer demand write a trivial JDBC language sentence, make data last long thus the layer got biggest of simplification.
