The relation mapping framework has taken Java to undreamed high level in the past few years. Before knowing more about Hibernate, you need to know that persistence layer is a demanding feature used by any enterprise application to store, manipulate & retrieve the data from database. So the motto of using Hibernate comes here. Yes, Hibernate helps you to eliminate the space between the object oriented programming and relational database model that sits in the persistence layer.
So Hibernate enable the developer to explore the power of natural Java to access the persistence layer without referring to too many SQLs in the code. Hibernate helps us in integrating with database using Java code itself, thereby reducing the time consumption & expense spend on changing the underlying database schema.
Our intensive & practical oriented Hibernate training in at Live Technoworld in Gurgaon will definitely provide the delegates with knowledge necessary to develop Java applications that rely on Hibernate for persistence solution.
